Yes, it's a module for RDFa that is conformant with XHTML
Modularization 1.1 [1]. The module will be available for incorporation
with any other language that uses M12N, not just XHTML and as such
Shane McCarron is kindly working with us to produce a document that
describes this 'standalone' M12N module, and its use.

As it happens, XML Schemas to do all of this have been around for a
while [2], and that includes validating RDFa. However, they've not
been 'officially' released, because the work I did to create them (for
XForms, SVG and RDFa) was then fed back into the M12N structure. So
all that's happening at the moment is that we're going back around the
loop again, and 'recreating' the schemas based on the new M12N
foundation, rather than the original one I used. (Basically, to cope
with the compound document format we wanted, the original schemas had
to be changed.) Also, these changes to M12N affected XHTML 1.1, so
there has been a new release of that [3]. But we've been popping back
up the stack, so everything will be available very soon!

To re-cap, the architecture is as follows:

 * XHTML Modularization 1.1 provides the general structure;

 * a new version of XHTML 1.1 has been released that incorporates the
   changes recently made in M12N;

 * we have a set of RDFa schemas that conform to M12N;

 * we have a specification that describes these RDFa schemas, and also
   explains how to use them with any language built using M12N.

This latter component is the only one left to do, but it is almost complete.

Regards,

Mark
