    Interesting idea...
    But it didn't come out right in your email. See:
    http://lists.w3.org/Archives/Public/www-voice/2005JanMar/0030.html

Sorry. Unsure why, possibly the pgp signature.
schema within the message below.
  It ISO/IEC 19757-2, as defined at
http://www.y12.doe.gov/sgml/sc34/document/0362_files/relaxng-is.pdf

In order to cater for the constraints on phoneme attributes, I've used
the sun multi-scheme validator which embeds a schematron processor.
XSD can't hack it.
