Dan,

I think what Mike meant was explain the LEGAL syntax.  It will be no 
problem to describe what it *does*, you tell us how to say it.

Dan,

I'm unclear here.  Explain the illegal syntax?  I can explain AllDistinct
once we figure out how to say it.  Though its getting late to add a lot of
text to the Guide.  I still need to fix the datatype examples.

I realized the other day that this doesn't actually parse.
AllDistinct parses as a typedNode there, not a propertyElement.
parseType goes on propertyElements.

It seems Jos already made the point in his message

I don't think that's a show-stopper, but I suggest
the chair confirm that the guide editor can
explain how to use AllDistinc before making a decision
about AllDistinct.
