Paul wasn't speaking for the XML Core WG there.

Well, actually, no, it doesn't. On further reflection, I have more
concerns...

The use of attribute-like syntax in a PI is goofy.
test case:

  <?access-control allow = "voice.roadrunner.edu voice.acme.edu"?>

note the spaces. They are not allowed per the grammar in the spec,
but they would be allowed if it were an element. Is that by design?
Please add it to your test suite to make sure it's flagged as an
error by implementations, if so.

Also, it seems to me that access control is orthogonal
to VoiceXML. There's nothing about access control nor security in
the WG's charter. If there is security work going on, the security
community needs to be invited to participate.

Indeed, I am not satisfied and any request to advance should show my
outstanding dissent.
