RE: Last Call for XML Signature 2.0, Canonical XML 2.0 and XML Signature Streaming Profile of XPath 1.0

Jirka and others,

The XML Sig WG wants to know if we accept their response to one
of the comments we submitted.

I believe the crux is that Jirka questioned the need for another
XPath subset.  The XML Sig WG:

> ... discussed the rationale for an additional profile at the 2010 TPAC
> and Pratik has sent a message in response to this comment, see
> http://lists.w3.org/Archives/Public/public-xmlsec/2011Jun/0013.html

So the question is whether we accept this response and, if not, what
we want to suggest to resolve the issue.

thoughts?
