Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http: This is one document in a set of eight documents that are being progressed to Edited Recommendation together XPath 2. This second edition is not a new version of this specification; its purpose is to clarify a number of issues that have become apparent since the first edition was published.

All of these clarifications excepting trivial editorial fixes have been published in a separate errata document, and published in a Proposed Edited Recommendation in April, The changes are summarized in an appendix. This document has been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and is endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited from another document.

W3C’s role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This enhances the functionality and interoperability of the Web. This document incorporates changes made against the Recommendation of 23 January that resolve all errata known at the date of publication. A list of the errata that have been applied, with links to the Bugzilla database, is provided in F Changes since the First Edition. The version of this document with change highlighting indicates where the textual changes have been made, and cross-references each textual change to the erratum where it originated.

This document supersedes the first edition. This specification is designed to be referred to normatively from other specifications defining a host language for it; it is not intended to be implemented outside a host language. The implementability of this specification has been tested in the context of its normative inclusion in host languages defined by the XQuery 1. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the XML Query Working Group and also maintains a public list of any patent disclosures made in connection with the deliverables of the XSL Working Group; those pages also include instructions for disclosing a patent.

An individual who has actual knowledge of a patent which the individual believes contains Essential Claim s must disclose the information in accordance with section 6 of the W3C Patent Policy. QName and xs: The purpose of this document is to catalog the functions and operators required for XPath 2. This document defines constructor functions and functions that take typed values as arguments. Some of the functions define the semantics of operators discussed in [XQuery 1.

Datatypes Second Edition] defines a number of primitive and derived datatypes, collectively known as built-in datatypes. This document defines functions and operations on these datatypes as well as the datatypes defined in Section 2. This document also discusses functions and operators on nodes and node sequences as defined in the [XQuery 1.

References to specific sections of some of the above documents are indicated by cross-document links in this document. Each such link consists of a pointer to a specific section followed a superscript specifying the linked document. The superscripts have the following meanings: The Functions and Operators specification is intended primarily as a component that can be used by other specifications.

Authors of conformance criteria for the use of the Functions and Operators should pay particular attention to the following features:. This means that datatypes such as xs: NCName and xs: ID are constrained by the XML 1. Authors of conformance requirements for the use of Functions and Operators should state clearly the implications for conformance of any changes to the rules in later versions of XML Schema.

In this document, text labeled as an example or as a Note is provided for explanatory purposes and is not normative. The functions and operators discussed in this document are contained in one of three namespaces see [Namespaces in XML] and referenced using an xs: Datatypes Second Edition] and in Section 2. The namespace prefix used in this document for functions that are available to users is fn.

Operator functions are named with the prefix op. This document uses the prefix err to represent the namespace URI http: This namespace prefix is not predeclared and its use in this document is not normative. The namespace prefix used for the functions, datatypes and errors can vary, as long as the prefix is bound to the correct URI.

The namespace URI associated with the err prefix is not expected to change from one version of this document to another. The contents of this namespace may be extended to allow additional errors to be returned. The functions defined with an fn prefix are callable by the user. These functions are not available directly to users, and there is no requirement that implementations should actually provide these functions.

For this reason, no namespace is associated with the op prefix. In general, the specifications named above do not support function overloading in the sense that functions that have multiple signatures with the same name and the same number of parameters are not supported. In addition, it should be noted that the functions defined in 6 Functions and Operators on Numerics that accept numeric parameters accept arguments of type xs: See 1.

This document does define some functions with more than one signature with the same name and different number of parameters. User-defined functions with more than one signature with the same name and different number of parameters are also supported. Each function is defined by specifying its signature, a description of the return type and each of the parameters and its semantics.

For many functions, examples are included to illustrate their use. In this notation, function-name , in bold-face, is the name of the function whose signature is being specified. If the function takes no parameters, then the name is followed by an empty parameter list: If there are two or more parameter declarations, they are separated by a comma. The return-type , also in italics, specifies the static type of the value returned by the function.

The dynamic type returned by the function is the same as its static type or derived from the static type. All parameter types and return types are specified using the SequenceType notation defined in Section 2. In some cases the word ” numeric ” is used in function signatures as a shorthand to indicate the four numeric types: For example, a function with the signature:. For most functions there is an initial paragraph describing what the function does followed by semantic rules. These rules are meant to be followed in the order that they appear in this document.

In some cases, the static type returned by a function depends on the type s of its argument s. These special functions are indicated by using bold italics for the return type. The semantic rules specifying the type of the value returned are documented in the function definition. The rules are described more formally in Section 7. Datatypes Second Edition] and must adhere to its syntactic conventions.

Datatypes Second Edition] datatype name, it may have intercapitalized spelling and is used in the function name as such. For example, fn: Rules for passing parameters to operators are described in the relevant sections of [XQuery 1. For example, the rules for passing parameters to arithmetic operators are described in Section 3.

Specifically, rules for parameters of type xs: As is customary, the parameter type name indicates that the function or operator accepts arguments of that type, or types derived from it, in that position. This is called subtype substitution See Section 2. In addition, numeric type instances and instances of type xs: See Section B. Subtype Substitution: A derived type may substitute for its base type.

In particular, xs: Numeric Type Promotion: Promotion to xs: A value of type xs: Some functions accept a single value or the empty sequence as an argument and some may return a single value or the empty sequence.

Relative dating is the science of determining the relative order of past events fossils) are fossils used to define and identify geologic periods (or faunal stages). A technique used to determine the actual age of a fossil a method of determining the absolute age of an object by comparing the relative percentages of a.

Behavioral modernity [1] is a suite of behavioral and cognitive traits that distinguishes current Homo sapiens from other anatomically modern humans , hominins , and primates. Although often debated, most scholars agree that modern human behavior can be characterized by abstract thinking, planning depth, symbolic behavior e. Some of these human universal patterns are cumulative cultural adaptation, social norms, language, and extensive help and cooperation beyond close kin. Arising from differences in the archaeological record, a debate continues as to whether anatomically modern humans were behaviorally modern as well.

Коммандер. Стратмор даже не повернулся.

Он искал глазами открытую дверь или ворота – любой выход из этого бесконечного каньона, – но ничего не. Улочка начала сужаться. – Soccoro! – Его голос звучал еле слышно.

Перстня. – Да. Взгляните. Офицер подошел к столу. Кожа на левой руке загорелая, если не считать узкой светлой полоски на мизинце.

Всю ответственность я беру на. Быстрее. Хейл выслушал все это, не сдвинувшись с места и не веря своим ушам. Хватка на горле Сьюзан слегка ослабла. Стратмор выключил телефон и сунул его за пояс. – Твоя очередь, Грег, – сказал. ГЛАВА 81 С мутными слезящимися глазами Беккер стоял возле телефонной будки в зале аэровокзала. Несмотря на непрекращающееся жжение и тошноту, он пришел в хорошее расположение духа.

Нужно решать, сэр! – требовал Джабба.

Партнер Танкадо – призрак. Северная Дакота – призрак, сказала она. Сплошная мистификация.

Она попыталась собраться с мыслями. – Сегодня суббота, сэр. Обычно мы… – Знаю, – спокойно сказал.  – Но ситуация чрезвычайная. Сьюзан встала. Чрезвычайная ситуация. Она не помнила, чтобы это слово срывалось когда-нибудь с губ коммандера Стратмора. Чрезвычайная. В шифровалке. Она не могла себе этого представить.

Я поменялся сменой с новым сотрудником. Согласился подежурить в этот уик-энд. Глаза Стратмора сузились. – Странно. Я вчера говорил с. Велел ему сегодня не приходить. Он ничего не сказал о том, что поменялся с тобой дежурством.

– Я опытный диагност. К тому же умираю от любопытства узнать, какая диагностика могла заставить Сьюзан Флетчер выйти на работу в субботний день. Сьюзан почувствовала прилив адреналина и бросила взгляд на Следопыта. Она понимала, что не может допустить, чтобы Хейл его увидел, – последует слишком много вопросов. – Я хочу сохранить это в тайне, – сказала. Но Хейл продолжал приближаться. Когда он был уже почти рядом, Сьюзан поняла, что должна действовать.

Какой тип? – Беккер хмуро взглянул на полицейского. – Тот, что вызвал скорую. Он болтал что-то на ужаснейшем испанском, который мне только доводилось слышать. – Он сказал, что на руке у мистера Танкадо было кольцо. Офицер кивнул, достал из пачки Дукадо сигарету, посмотрел на плакат с надписью No fumar – Не курить – и все же закурил.

El vuelo a los Estados Unidos. Стоявшая за стойкой симпатичная андалузка посмотрела на него и ответила с извиняющейся улыбкой: – Acaba de salir. Вы на чуть-чуть опоздали.  – Ее слова словно повисли в воздухе. Все-таки он опоздал. Плечи Беккера обмякли.

Капля Росы. Вы уверены. Но Пьер Клушар провалился в глубокое забытье. ГЛАВА 23 Сьюзан, сидя в одиночестве в уютном помещении Третьего узла, пила травяной чай с лимоном и ждала результатов запуска Следопыта. Как старшему криптографу ей полагался терминал с самым лучшим обзором.
