Identifiers for XSLT 2.0 and XPath 2.0 in XML Signature spec

The XML Signature spec indicates the identifiers for using XSLT 1.0 and
XPath 1.0 as transforms. Should we not also include those for XSLT 2.0 and
XPath 2.0 now that those are released (and will generally be more commonly
used now)? Or is that something for v2.0 of XML Signature?
 
FYI, I'm having vague recollections that fundamental changes to the nature
of XPath between XPath 1.0 and XPath 2.0 may affect the text we have in the
XML Signature spec re XPath. I will continue to contemplate this.
