Thanks for providing the information regarding the Unicode reference  
in the XML Signature, Second Edition PER.

We discussed this issue on today's working group call and came to the  
conclusion that we should remove the Unicode reference from the  
document [1]. This should remove the possibility of any  
misinterpretation of the reference and not raise any false implications.

The rationale is that the reference is not normative, not referred to  
in the document, and not very precise as it refers to a web page and  
may be misinterpreted. The Working Group felt that the best approach  
is to allow the XML specification to refer to Unicode appropriately.

This decision by the working group should close this issue.

If you have any concerns please respond to this email including the  
public-xmlsec-maintwg mail address as a recipient. If we hear nothing  
we will assume that the response is acceptable, but would prefer an  
acknowledgment that this is acceptable.

Thank you

regards, Frederick
