Character normalization

All,

I have been looking even deeper into the unicode issues.

One aspect which matters for string operations is character 
normalization. In unicode, for compatibility reasons, some characters 
can be represented as either a single character, or a sequence of 
characters which compose into a single character. Character 
normalization means converting them into canonical form.

The friendly people at W3C have written the following document which is 
intended to help, among others, writers of specifications:

http://www.w3.org/TR/2005/WD-charmod-norm-20051027/

I suggest that XACML 3.0 be made to conform to this.

Regards,
Erik
