Dear all,

we can live with the text as proposed by Thomas with a small change. 

	The original edition of this specification [XMLDSIG-2002]
	referenced the XPointer Candidate Recommendation
	[XPTR-2001].  That Candidate Recommendation has been
	superseded by the [xptr-fwk], [xptr-xmlns] and
	[xptr-element] Recommendations, and -- at the time of this
	edition -- the [xptr-xpointer] Working Draft.  Therefore,
	the use of the xpointer() scheme beyond the usage discussed 
        in this section is discouraged.


s/"support of xpointer()"/"the use of xpointer()"/
s/"minimal usage"/"useage"/

We however would still like to mention that we would appreciate some remark making verifiers aware of the fact the there are existing signatures in deployed systems making use of the optional xpointer() scheme.

We think the text could benefit a change to the first sentence.

	The original edition of this specification [XMLDSIG-2002]
	referenced the XPointer Candidate Recommendation
	[XPTR-2001] and some implementations support it optionally.
	
We think this would also add clarity.

regards
Konrad
A-SIT
