The context element is in particular useful when we like to allow a
embedded vocabulary to occur just in a certain context of the parent
vocabulary. Let's consider we have a XHTML document which can contain
some meta-data expressed using RDF. As meta-date are not intended to be
rendered, we don't want them to occur in the document's body.

So rather than despatching on the rdf namespace, it is further
constrained by the context... which is quite similar to Ricks
description for Schematron! Spooky.

 <validate schema="xhtml.rng">
        <context path="head"
                 useMode="rdf"/>
      </validate>

 <mode name="rdf">
....

So the transition will only occur (the mode is constrained to?) when the
current context (as per xslt context) matches local-name() = 'head' in
the 'current' namespace.

Certainly makes sense.

Thanks Jirka... and Petr?

regards
