expanded-QName

From XQuery 1.0 and XPath 2.0 Data Model (XDM) (2007-01-23) | Glossary for this source

An expanded-QName is a set of three values consisting of a possibly empty prefix, a possibly empty namespace URI, and a local name.
explicit expiration time

From Hypertext Transfer Protocol -- HTTP/1.1 (1999-06-15) | Glossary for this source

The time at which the origin server intends that an entity should no longer be returned by a cache without further validation.
explicit user request

From User Agent Accessibility Guidelines 1.0 (2002-12-17) | Glossary for this source

In this document, the term "explicit user request" refers to any user interaction through the user agent user interface (not through rendered content), the focus, or the selection. User requests are made, for example, through user agent user interface controls and keyboard bindings.Some examples of explicit user requests include when the user selects "New viewport," responds "yes" to a prompt in the user agent's user interface, configures the user agent to behave in a certain way, or changes the selection or focus with the keyboard or pointing device.Note: Users make mistakes. For example, a user may inadvertently respond "yes" to a prompt instead of "no." In this document, this type of mistake is still considered an explicit user request.
expression context

From XQuery 1.0: An XML Query Language (2007-01-23) | Glossary for this source

The expression context for a given expression consists of all the information that can affect the result of the expression.
expression context

From XML Path Language (XPath) 2.0 (2007-01-23) | Glossary for this source

The expression context for a given expression consists of all the information that can affect the result of the expression.
extended language

From Architecture of the World Wide Web, Volume One (2004-12-15) | Glossary for this source

If one language is a subset of another, the latter is called an extended language.
extended link

From XML Linking Language (XLink) (2001-06-27) | Glossary for this source

An extended link is a link that associates an arbitrary number of resources. The participating resources may be any combination of remote and local.
extended links

From XML Linking Language (XLink) (2001-06-27) | Glossary for this source

Extended links offer full XLink functionality, such as inbound and third-party arcs, as well as links that have arbitrary numbers of participating resources. As a result, their structure can be fairly complex, including elements for pointing to remote resources, elements for containing local resources, elements for specifying arc traversal rules, and elements for specifying human-readable resource and arc titles.XLink defines a way to give an extended link special semantics for finding linkbases; used in this fashion, an extended link helps an XLink application process other links.
extending pre-defined elements

From Modularization of XHTML (2001-04-10) | Glossary for this source

In some instances, a module adds attributes to an element. In these instances, the element name is followed by an ampersand (&).
extensible

From QA Framework: Specification Guidelines (2005-08-17) | Glossary for this source

The ability of a specification to accept extensions in a defined way. A specification is extensible if it provides a mechanism for any party to create extensions.
extensible markup language (XML)

From Mathematical Markup Language (MathML) Version 2.0 (2001-02-21) | Glossary for this source

A simple dialect of SGML intended to enable generic SGML to be served, received, and processed on the Web.
extensible style language (XSL)

From Mathematical Markup Language (MathML) Version 2.0 (2001-02-21) | Glossary for this source

A style language for XML developed by W3C. See XSL FO and XSLT.
extension

From QA Framework: Specification Guidelines (2005-08-17) | Glossary for this source

The ability to incorporate additional functionality beyond what is defined in the specification. It broadens the possibility of the technology.
extension attributes

From XSL Transformations (XSLT) 2.0 (2007-01-23) | Glossary for this source

An element from the XSLT namespace may have any attribute not from the XSLT namespace, provided that the expanded-QName (see ) of the attribute has a non-null namespace URI. These attributes are referred to as extension attributes.
extension expression

From XQuery 1.0: An XML Query Language (2007-01-23) | Glossary for this source

An extension expression is an expression whose semantics are implementation-defined.
extension function

From XSL Transformations (XSLT) 2.0 (2007-01-23) | Glossary for this source

An extension function is a function that is available for use within an XPath expression, other than a core function defined in , an additional function defined in this XSLT specification, a constructor function named after an atomic type, or a stylesheet function defined using an xsl:function declaration.
extension instruction

From XSL Transformations (XSLT) 2.0 (2007-01-23) | Glossary for this source

An extension instruction is an element within a sequence constructor that is in a namespace (not the XSLT namespace) designated as an extension namespace.
extension namespaces

From XSL Transformations (XSLT) 2.0 (2007-01-23) | Glossary for this source

The extension instruction mechanism allows namespaces to be designated as extension namespaces. When a namespace is designated as an extension namespace and an element with a name from that namespace occurs in a sequence constructor, then the element is treated as an instruction rather than as a literal result element.
extensional

From RDF Semantics (2004-02-10) | Glossary for this source

(adj., of a logic) A set-based theory or logic of classes, in which classes are considered to be sets, properties considered to be sets of <object, value> pairs, and so on. A theory which admits no distinction between entities with the same extension. See Intensional .
external

From Hypertext Terms (1995-04-15) | Glossary for this source

A link to a node in a different database. See Database
