Associating a GRDDL transform with an XML schema... and it's not XSLT

Hi,

As some of you on this list area aware, POWDER associates a GRDDL 
transform with its namespace, the result of which produces POWDER-S. 
(POWDER is an XML dialect, POWDER-S is RDF/OWL with a twist).

The transform is defined in our Formal Semantics document [1], currently 
undergoing minor edits to take account of LC comments received. What I'm 
working on right now is getting the right references in the right places 
to make the GRDDL association explicit... and, sorry, I'm confused and 
would greatly appreciate some help.

We have a (rather complicated) schema at [2]. We have a GRDDL transform 
defined as human-readable text at [1].

Do we just add a couple of lines like this to the root element of the 
schema?

xmlns:data-view="http://www.w3.org/2003/g/data-view#"
data-view:transformation="http://www.w3.org/TR/powder-formal/"

I ask because the Primer suggests this is enough [3] but the main 
documentation [4] suggests we need to include a chunk of RDF as an 
xsd:annotation.

And given that the normative transform is defined in a human readable 
document, not an XSLT, is this going to break something? Actually, we do 
have an XSLT but a) it's not normative and b) it handles some, but not 
all of the transform (see the thread starting at [5] if you care why).

Any and all comments gratefully received.

Thanks

Phil.
