I see.  During the last teleconference there was some uncertainty as to 
what 'hooks' were registered in the schema to identify transforms with 
for its instances, the http://www.w3.org/2003/g/po-ex schema makes it 
clear.  I'm not sure if it's a lack of implementation detail that's the 
issue but rather the wording:

"Since the XML instance documents are often distributed, as in 
the OAI case, the XML schema (residing at the namespace location) could 
embed RDF descriptions identifying a transform to apply to all its 
instance documents."                              ^^^^^

'apply' could be a link to the appropriate place in the specification that 
outlines how this is done: http://www.w3.org/2004/01/rdxh/spec#ns-bind

Perhaps even some mention of the existing general-purpose transform 
http://www.w3.org/2003/g/embeddedRDF.xsl which allows you to extract 
embedded RDF/XML directly via:

data-view:transformation="http://www.w3.org/2003/g/embeddedRDF.xsl"
