Problems with the latest schema

There are some inconsistencies between the specification text and the
"snapshot" of the schema Alex sent out April 29th.

  
<if><then>. The production for <if> includes a
<then> element, where the specification just calls for an activity.

  
tExtensionActivity has had a namespace attribute added to the any
child. There is no mention of this, as far as I can find, in the latest
draft specification. (If this an attempt to say ##other?)

Cheers,
