XHTML Modularization in RNG (was: Best Practice - Vanilla XML?)

Furthermore, at http://thaiopensource.com/relaxng/xhtml there is available
a RELAX NG version of XHTML modularization; not a conversion of the DTD,
but a rebuilt version designed for convenient RNG use.

You can mix in your own attributes and elements very easily using the
combine-by-interleaving feature of RNG.  For example, to add an element
named "rdf:RDF" to the model of "xhtml:head", you just write:

<define name="head.content" combine="interleave">
  <element ns="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; name="RDF">
    <ref name="rdf.model"/>
  </element>
</define>

Or in the compact syntax:

head.content &= element rdf:RDF { rdf.model }
