Yes, it definitely is.

First, it borrows "character class expressions (for example [b-y]) and category
escapes (for example \p{Ll} for all lowercase letters)" from W3C XML Schema
I think that this is a good idea. My only comment is that we have to specify
the version number of Unicode, since different versions of Unicode are just
different.

Second, it can specify impose a character-repertoire-constraint on element names
and can impose another on attribute names, and yet another on attribute
values, etc. I think that this is a good idea. But I do am not sure if
we should allow constraints on comments or PIs.

Third, constraints have scopes, which are specified by XPath. Although this
is useful (e.g., p[@xml:lang = "en"]) , I feel a bit uneasy about this. Should
we rather rely on Part 10?

Cheers,

Makoto
