Rick proposes an interesting model. This model is largely already supported in XHTML Modularization. XHTML Modularization provides a toolkit for developing markup languages from modules. These modules are defined abstractly, and then mapped onto an implementation (an XML DTD, but an XML Schema is also possible). These modules can be collected together to form arbitrary XHTML-family markup languages. Users can also develop new modules with their own elements and attributes, extend the content models of XHTML-provided modules, etc. These are defined in Building XHTML Modules, Modularization of XHTML, and XHTML 1.1. These public documents are available at http://www.w3.org/TR The working group never intended XHTML 1.0 to be extensible. It is a bridge. It is there to help HTML document authors make the transition to XML in a way that is backward compatible with existing browsers. Nothing more. Don't read too much into it. It will drive you crazy. With regard to namespaces, IMO the work on Modularization is orthogonal to namespaces. It is not the intent of the working group to define multiple namespaces within the modularization infrastructure. You could, I supposed, use modularization to define a collection of namespaces that represent different collections of functionality. These namespaces could then be cobbled together in compound documents. However, the resulting documents would not be validatable. Regardless, the modularization architecture of XHTML is designed to address the goal of extensibility on a massive scale. It can be mapped into XML Schema or XML DTDs. It can rely upon XML namespaces or not. I suggest you all check these documents out before worrying about the extensibility of XHTML. -- Shane P.
