I recognise we'd like to GRDDL done and put to bed.  However, I'd like
to test support for the following.

The transforms to be applied to an XML document can be specified in the
document itself or in a schema document.  It may be helpful for an XML
document to also nominate another document in which the transforms to be
applied are specified.  This would allow a collection of documents to
refer to a single, non-schema document that specified applicable
transforms.  Then, when a new transform became available, or an existing
transform was no longer applicable, a single document could be updated.

The feature might be accomplished with a new rule along the following

If G is a GRDDL result of the information resource IR and G contains the

  IR grddl:transform 
   [ grddl:mime-type MT ;
     rdf:value       T ] .

Then T is a GRDDL transform of representations of IR of mime-type MT.

I note that is a generalized way to assert in RDF that a transform
applies to a resource representation.  This could also be used to
specify third party transforms.
