Henry checked, and indeed it does, for XML 1.1 input.

See
http://www.cogsci.ed.ac.uk/~richard/rxp.html
and the Unix man page for it at
http://www.cogsci.ed.ac.uk/~richard/rxp.txt

There is a -U flag that controls Unicode normalization
checking and is only relevant when parsing XML 1.1 documents.
If it is 0, no checking is done.  If it is 1, rxp checks
that the document is fully normalized as defined by the
W3C character model.  If it is 2, the document is checked
and any unknown characters (which may be ones corresponding
to a newer version of Unicode than rxp knows about) will
also cause an error.

For example, given

c.xml:
<c>&#x338;</c>

you can do the following:

  > (echo "<?xml version='1.1'?>" ; rxp c.xml)|rxp  -U 1
  <?xml version="1.1" encoding="UTF-8"?>
  Error: pcdata not normalized
   in unnamed entity at line 2 char 6 of <stdin>

>
> ACTION to Henry, John:  Read Paul's draft response at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2013Mar/0005
> and comment.

Henry and John both read it and had no comments.


ACTION to Paul:  Update the draft with the mention of RXP
and send it to Roger and the xml-editor list.
