XHTML Modularization
The XHTML modularization model defines the modules of XHTML.
Why XHTML
Modularization?
XHTML is a simple
but large language, containing most of the
functionality a web developer will need.
For some purposes
XHTML is too large and complex, and for other
purposes it is much too simple.
By splitting XHTML
into modules, the W3C (World Wide web Consortium)
has created small and well-defined sets of XHTML
elements that can be used separately for simple
devices as well as combined with other XML standards
into larger and more complex applications.
With modular XHTML,
product and application designers can:
-
Choose the
elements to be supported by a device using
standard XHTML building blocks.
-
Add extensions
to XHTML, using XML, without breaking the XHTML
standard.
-
Simplify XHTML
for devices like hand held computers, mobile
phones, TV, and home appliances.
-
Extend XHTML
for complex applications by adding new XML
functionality (like MathML, SVG, Voice and
Multimedia).
-
Define XHTML
profiles like XHTML Basic (a subset of XHTML for
mobile devices).
