4. XHTML DTD Modules
This section is normative.
This section specifies the XHTML DTD modules, the type declarations
found in each module, and the file and parameter entity naming conventions
used throughout the DTD.
4.1. Implementing Document Model Modules in the DTD
Partitioning of
the document model occurs at the semantic module level. This partitioning
is implemented in the markup model by two primary methods:
parameterization, the use of parameter entities as
reusable strings, and modularization, the
creation of DTD fragments called modules.
4.1.1. Parameterization
This specification classifies parameter entities into six categories and names
them consistently using the following suffixes:
- .mod
- parameter entities use the suffix
.mod when they are used
to represent a DTD module (a collection of element classes). In this
specification, each module is an atomic unit and may be represented as a
separate file entity.
- .module
- parameter entities use the suffix
.module when they are used
to control the inclusion of a DTD module by containing either of the conditional
section keywords INCLUDE or IGNORE.
- .content
- parameter entities use the suffix
.content when they are used
to represent the content model of an element type.
- .class
- parameter entities use the suffix
.class when they are used
to represent elements of the same class.
- .mix
- parameter entities use the suffix
.mix when they are used to
represent a collection of element types from different classes.
- .attrib
- parameter entities use the suffix
.attrib when they are used
to represent a group of tokens representing one or more complete attribute
specifications within an ATTLIST declaration.
For example, in HTML 4.0, the %block; parameter entity is defined
to represent the heterogenous collection of element types that are block-level
elements. In this specification, the corollary parameter entity is
%Block.mix;.
4.1.2. Modularization
DTD modules are often used to encompass the markup declarations
of a specific semantic component or "feature", from higher-level document
features like tables and forms, to lower-level components such as specific
elements or element groups. Modules can even contain modules, creating a
hierarchical structure mirroring the document model. Note that modules
are not always implemented as separate file entities, and modular DTDs
can be easily normalized into single file versions for more efficient
distribution over the Web.
The relationship between document model components and how they are implemented
in markup as modules, entities and files (i.e., the granularity of the
parameterization or modularization, how the markup model is structured and
stored as separate entities, etc.) is not necessarily direct, as design style
and implementation issues properly play a part. Higher-level modules are sometimes
delivered as individual file entities to facilitate portability and reusability.
To promote interoperability, the XHTML DTD design considers each module as atomic,
with the notion that implementations should support the semantics of an entire
module without further subdivision.
While the notion of "plug and play" with DTD modules is very attractive,
in practice this is not quite so simple. Complex document models often resort to
extensive parameterization of semantic modules to facilitate understanding,
markup reuse, extensibility, and maintenance. The resultant modules may have
have many interdependencies, and may require a fair amount of "rewiring"
when adding or removing a DTD module. In light of this, a compromise must be made
between markup flexibility, complexity of the DTD, and ease of maintainability.
The XHTML DTD attempts to ameliorate this by localizing many of the more
"global" parameter entities to several modules that are declared
early in the DTD. These are labelled common
modules, and include declarations for common names, attributes, parameter and
character entities.
XHTML elements are classified into the following categories:
- structural element types
- element types that create the overall structure of an XHTML document.
- block element types
- element types that should cause a line break.
- inline element types
- element types that are displayed inline to an existing block.
- phrasal element types
- element types that specify a domain-relevant connotation
- presentational element types
- element types that indicate a desire on the part of the author for a specific
rendering effect.
- special case (or "feature") element types
- element types that provide XHTML with special features, such as linking,
forms, etc.
Following is a module-by-module catalog of element types and
parameter entities declared in the three XHTML DTDs, what
constitutes in effect the XHTML namespace.

documentation is also available for each of the three XHTML 1.0 DTDS:
