Hello Mark, dear XSL WG,

The I18N WG has made quite some progress on a lot of the issues
raised in the 2nd last call of the Character Model.
However, we still have a few open issues; we hope to be done
with them very soon.

One more such issue is:

XSL WG Comments on Character Model WD

     * Comment (received 2002-06-28) -- XSL WG Comments on Chairacter Model WD

       "[S] [I] A text-processing component that receives suspect text MUST NOT
        perform any normalization-sensitive operations unless it has first
        confirmed through inspection that the text is in normalized form, and
        MUST NOT normalize the suspect text. Private agreements MAY, however,
        be created within private systems which are not subject to these rules,
        but any externally observable results MUST be the same as if the rules
        had been obeyed."

       The exception for private agreements is crippled by the observable 
results
       restriction thus when all is said and done any suspect text will 
always remain.

     * Decision: Clarify that "externally observable" refers to both inputs 
and outputs.
     * Decision: Ask originator(s) to clarify the comment.

We did not really understand your comment. We assume that
a system receives only normalized text, and produces only
normalized text. Nevertheless, it is possible that internally,
it stores all the texts as fully decomposed, trancoding both
on input and on output. We do not understand how in this
example, 'exception for private agreements is crippled by
the observable results restriction'. There is no problem
with using fully decomposed text as the storage format.

Can you please clarify your comment, so that we are sure we
understand each other?

Regards,     Martin.
