XHTML modularization is a methodology for producing modularized markup languages in a number of different schema languages so that the modules can easily be plugged together to create markup languages.
Method
XHTML Modularization consists of three essential parts • a technique or methodology (as explained, actually independent of XHTML, and applicable to any XML-based markup language) for defining abstract modules of a markup language, and implementing those modules in various schema languages, such as DTDs, XML Schema, and Relax NG. • a collection of abstract modules • a number of implementations of those modules in various schema languages. To define a language using these modules, you only have to define a driver in one or more of the implementation schema languages, that causes the necessary modules to be loaded. ==Application to XHTML==
Application to XHTML
In its application to XHTML, it provides a means for defining modules of XHTML to allow subsetting and extending XHTML in a controlled way. Core modules are: • Structure (html, head, body, title...) • Text (h1, h2, h3... p, pre...) • Hypertext (a) • List (ul, li...) Other modules include applet, image, forms and basic forms. == References ==
