Too difficult? loop test

Summary:

concerning
http://www.w3.org/2001/sw/grddl-wg/td/pendinglist#loopx
I think this is significantly harder than what the WG intends, and may 
merit a substantive change to the spec.

********************


I wrote the following test, which the Jena GRDDL reader fails.
http://www.w3.org/2001/sw/grddl-wg/td/pendinglist#loopx

An XML document is its own namespace document, with grddl 
transformation, specifying a namespaceTransformation, which specifies a 
further namespaceTransformation.

i.e.
http://www.w3.org/2001/sw/grddl-wg/td/loopx
has a GRDDL result being:
<> g:namespaceTransformation <loopx.xsl> .

from the embeddedRDF  transform.

By looking at its namespace doc, which is itself,
it has a grddl result being

<> g:namespaceTransformation <loopy.xsl> .

Hence, by looking (one again?) at its namespace doc, it has a GRDDL result

<> g:namespaceTransformation <one.xsl> .

Hence, by looking (yet again?) at its namespace doc, it has a GRDDL result

_:a rdf:value "one" .

This gives
http://www.w3.org/2001/sw/grddl-wg/td/loopx-output

The jena grddl reader, doesn't keep looking again, and so only finds the 
first two triples.

I think this is significantly harder than what the WG intends, and may 
merit a substantive change to the spec.
