What are the XHTML-Print operations that are affacted by normalization?
This discussion is useful for string processing (match, substring, sort)
but I don't see how that affects printing. One possible area is CSS class
names; are they restricted to ASCII?
Also, I don't see how a new report can change the definition of an existing
spec (XHTML). Isn't this a separate set of rules that might be folded into
future revisions?
I would rather see a use-case that makes sense for XHTML-Print before
adding this in.
E.
P.S. Does it have any effect on current CR documents? I don't think so.
There is no discussion of combining in there at all.

Hello,
I've been reading the W3C Working Draft, Character Model for the World Wide
Web [1], which deals with requires of internet applications should as
producers and consumers of XHTML-Print.
This report [1] indicates that XHTML-Print as a derivate of XHTML is bound
by it. Therefore, by extension, all XHTML-Print producing and consuming
applications are bound by this report all thought this is never explicitly
stated in any version of the XHTML-Print specification [2,3].
One of the interesting parts of [1] is the requirement that applications
that produce XHTML-Print should produce fully-normalized text [4] meaning,
among other things, that it is in Unicode Normalized Form C [5], which
favors the canonical composite forms of Unicode characters.
>From the printer's perspective, as a receiver of XHTML-Print documents,
this
makes its job easier since it can always assume that text is
fully-normalized and it doesn't have to do so itself.
My question to you is, do you think that the XHTML-Print specification
should be amended to site the requirement that a conforming XHTML-Print
document be fully-normalized? Furthermore, should a printer be required to
check an XHTML-Print document to see that it is fully-normalized or should
it assume so? Lastly, should a printer normalize text that is not
fully-normalized or discard it?
