Ed, you are right.

Just to clarify, we don't guarantee "must". The abridged presentation syntax
is non-normative. 

We need it as a compact readable and uniform language to present examples in
RIF documents such as Use Cases and Requirements or descriptions of Test

Of course, it can be used by people to present RIF rules, but it's up to
them. They will probably use their own platform-specific rule languages and
show how they map to the concrete XML syntaxes of the RIF dialects which are

I can agree with everything you say.  (OK, one caveat below.)

I'm only pointing out that although our job was only to see that the 
missiles go up, some are (rightly) concerned about where they may come down.

I completely agree.

It was never clear to me that the PS was part of that charter.

You are absolutely right that people who use the PS for instructive 
purposes SHOULD understand WHAT they are teaching.  But we can't 
guarantee "must", and some, perhaps many, won't.  That has been the 
experience in other such activities, e.g. CL, and that is why it was 
carefully avoided in OWL.

Yes.  Some important details, in fact.
