default mode

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

There is always a default mode available. The default mode is an unnamed mode, and it is used when no mode attribute is specified on an xsl:apply-templates instruction.
default namespace

From Namespaces in XML 1.1 (2004-02-04) | Glossary for this source

If the attribute name matches DefaultAttName, then the namespace name in the attribute value is that of the default namespace in the scope of the element to which the declaration is attached.
default namespace

From Namespaces in XML (1999-01-14) | Glossary for this source

If the attribute name matches DefaultAttName, then the namespace name in the attribute value is that of the default namespace in the scope of the element to which the declaration is attached.
default order for empty sequences.

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

Default order for empty sequences. This component controls the processing of empty sequences and NaN values as ordering keys in an order by clause in a FLWOR expression, as described in .
default priority

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

If no priority attribute is specified on the xsl:template element, a default priority is computed, based on the syntax of the pattern supplied in the match attribute.
deferred request authentication

From XML Key Management (XKMS 2.0) Requirements (2003-05-05) | Glossary for this source

A mechanism to allow a client to verify that the server processed the correct request. The client may verify the server response, for example, by comparing the elements returned in the response, or comparing a digest of the request with a digest returned in a secured response. This ensures that an attacker has not diverted or otherwise changed portions of a request. For example, a client request might be directed to a particular URI so that a specific policy will be enforced as part of the service processing the request. Inclusion of the URI in the response ensures that the expected server policy was followed and that the request was conveyed correctly.
defining element

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

A string in the form of a lexical QName may occur as the value of an attribute node in a stylesheet module, or within an XPath expression contained in such an attribute node, or as the result of evaluating an XPath expression contained in such an attribute node. The element containing this attribute node is referred to as the defining element of the QName.
defining required attributes

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

When an element requires the definition of an attribute, that attribute name is followed by an asterisk (*).
defining the type of attribute values

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

When a module defines the type of an attribute value, it does so by listing the type in parentheses after the attribute name.
deflate

From Portable Network Graphics (PNG) Specification (Second Edition) (2003-11-10) | Glossary for this source

name of a particular compression algorithm. This algorithm is used, in compression mode 0, in conforming PNG datastreams . Deflate is a member of the LZ77 family of compression methods. It is defined in [RFC-1951] .

From Portable Network Graphics (PNG) Specification (Second Edition) (2003-11-10) | Glossary for this source

depends

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

A function f1depends on a variable $y or a function f2 if a reference to $y or f2 appears in the body of f1, or if there exists a variable $z or a function f3 such that f1depends on $z or f3 and $z or f3depends on $y or f2.
A variable $xdepends on a variable $y or a function f2 if a reference to $y or f2 appears in the initializing expression of $x, or if there exists a variable $z or a function f3 such that $xdepends on $z or f3 and $z or f3depends on $y or f2.
deprecated

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