- abstract module
-
From Modularization of XHTML (2001-04-10)
a unit of document type specification corresponding to a distinct type of content, corresponding to a markup construct reflecting this distinct type.
- content model
-
From Modularization of XHTML (2001-04-10)
the declared markup structure allowed within instances of an element type. XML 1.0 differentiates two types: elements containing only element content (no character data) and mixed content (elements that may contain character data optionally interspersed with child elements). The latter are characterized by a content specification beginning with the "#PCDATA" string (denoting character data).
- content set
-
From Modularization of XHTML (2001-04-10)
Some modules define lists of explicit element names called content sets. When a content set is included in a content model, its name will be listed.
- defining required attributes
-
From Modularization of XHTML (2001-04-10)
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)
When a module defines the type of an attribute value, it does so by listing the type in parentheses after the attribute name.
- document model
-
From Modularization of XHTML (2001-04-10)
the effective structure and constraints of a given document type. The document model constitutes the abstract representation of the physical or semantic structures of a class of documents.
- document type
-
From Modularization of XHTML (2001-04-10)
a class of documents sharing a common abstract structure. The ISO 8879 [SGML] definition is as follows: "a class of documents having similar characteristics; for example, journal, article, technical manual, or memo. (4.102)"a formal, machine-readable expression of the XML structure and syntax rules to which a document instance of a specific document type must conform; the schema type used in XML 1.0 to validate conformance of a document instance to its declared document type. The same markup model may be expressed by a variety of DTDs.
- document type definition (DTD)
-
From Modularization of XHTML (2001-04-10)
a formal, machine-readable expression of the XML structure and syntax rules to which a document instance of a specific document type must conform; the schema type used in XML 1.0 to validate conformance of a document instance to its declared document type. The same markup model may be expressed by a variety of DTDs.
- driver
-
From Modularization of XHTML (2001-04-10)
a generally short file used to declare and instantiate the modules of a DTD. A good rule of thumb is that a DTD driver contains no markup declarations that comprise any part of the document model itself.
- element
-
From Modularization of XHTML (2001-04-10)
an instance of an element type.the definition of an element, that is, a container for a distinct semantic class of document content.
- element name
-
From Modularization of XHTML (2001-04-10)
When an element is included in a content model, its explicit name will be listed.
- element type
-
From Modularization of XHTML (2001-04-10)
the definition of an element, that is, a container for a distinct semantic class of document content.
- entity
-
From Modularization of XHTML (2001-04-10)
an entity is a logical or physical storage unit containing document content. Entities may be composed of parse-able XML markup or character data, or unparsed (i.e., non-XML, possibly non-textual) content. Entity content may be either defined entirely within the document entity ("internal entities") or external to the document entity ("external entities"). In parsed entities, the replacement text may include references to other entities.a mnemonic string used as a reference to the content of a declared entity (eg., "&" for "&", "<" for "<", "©" for "©".)
- entity reference
-
From Modularization of XHTML (2001-04-10)
a mnemonic string used as a reference to the content of a declared entity (eg., "&" for "&", "<" for "<", "©" for "©".)
- extending pre-defined elements
-
From Modularization of XHTML (2001-04-10)
In some instances, a module adds attributes to an element. In these instances, the element name is followed by an ampersand (&).
- generic identifier
-
From Modularization of XHTML (2001-04-10)
the name identifying the element type of an element. Also, element type name.
- hybrid document
-
From Modularization of XHTML (2001-04-10)
A hybrid document is a document that uses more than one XML namespace. Hybrid documents may be defined as documents that contain elements or attributes from hybrid document types.
- instantiate
-
From Modularization of XHTML (2001-04-10)
to replace an entity reference with an instance of its declared content.
- markup declaration
-
From Modularization of XHTML (2001-04-10)
a syntactical construct within a DTD declaring an entity or defining a markup structure. Within XML DTDs, there are four specific types: entity declaration defines the binding between a mnemonic symbol and its replacement content; element declaration constrains which element types may occur as descendants within an element (see also content model); attribute definition list declaration defines the set of attributes for a given element type, and may also establish type constraints and default values; notation declaration defines the binding between a notation name and an external identifier referencing the format of an unparsed entity.
- markup model
-
From Modularization of XHTML (2001-04-10)
the markup vocabulary (i.e., the gamut of element and attribute names, notations, etc.) and grammar (i.e., the prescribed use of that vocabulary) as defined by a document type definition (i.e., a schema) The markup model is the concrete representation in markup syntax of the document model, and may be defined with varying levels of strict conformity. The same document model may be expressed by a variety of markup models.
