Would RDFa support Named Graph ?

I have been looking around for a "recommended" solution to render Named
Graph in XHTML+RDFa syntax but with no luck.
I am not sure if this is the right place to raise this question. Or, if
this issue was already concluded previously in RDFa Work Group. I am sorry
if it was.

My use case originates from the Trust and Provenance of Semantic Data
Publishing. In such a case, we need to publish the RDF triples alongside
with its metadata, e.g. provenance and digital signature.
This can be done in TriG syntax by identifying the named graph and
specifying the relationship between graphs. However, if we want to render
the triples in XHTML+RDFa page, there is not a straight way to represent
the named graphs in RDFa syntax.

I've caught up with previous discussion between Mark Birbeck and Michael
Hausenblas at the link below.

As Mark made his point that RDFa is supposed to carry all triples from
single RDF graph and there is not need to put Named Graph in RDFa syntax. I
am wondering if this assumption has somehow restricted the expressivity of
RDFa, i.e. metadata with strong coherent relationship can not be published
within the same page of the document?

I am looking forward to your comment and suggestion. Further discussion and
information is warmly welcomed.
