Modular XHTML: XML Flexibility and Extensibility combined with HTML Familiarity
We have previously outlined the benefits of XML markup for general content and transforming it for web presentation, or the markup and presentation of all web content in XML thereby limiting the presentation of such content to web browsers and clients that support XML. The underlying idea of that suggestion was motivated by the need to maintain the fluid flexibility of XML in all web markup so that it should not become obsolete and require manual markup, or manual translation.
Modular XHTML
The concept and W3C draft of modular XHTML fills the need XHTML (version 1.1) makes it possible for device manufacturers, and platform designers to breakdown the single-block nature of XHTML 1.0 and rebuild it as a composition of the resulting sub-set of modules in addition to new custom modules that may be created to accommodate the extended needs to a particular device or content subjected (MathML as a specialized form of XHTML to represent mathematical relationships between values and variables).
A major advantage of using modular XHTML to represent web content is the reality that as long as the document has a valid driver and/or DTD, it will be understood and parsed by any XHTML capable client without the need to update that client with support for the new markup elements and attributes. The hierarchy and relationship between elements, and with new and existing attributes is defined by the DTD which is called at the beginning of the document.
Combination of Modules
As you may have already imaged it, one does not have to reinvent the wheel to create a custom Modular XHTML Language. Preexisting modules that are part of the standard XHTML 1.0, as well as other modules that have been created by others (for which there is an available DTD) can be combined and extended with other custom addition to create the markup needs at hand.
