I think even 9.1 is dangerous, it will raise questions such as 

why isn't it a requirement that 

Any meta data about any aspect of the Web Services reference
architecture should be expressible with an OMG approved language (such as
UML 
itself, MOF )

Why isn't it a requirement that it shall be expressible using Topic Maps?.

The intent of Web Services architecture clearly is not to make a judgement
on the format of choice for metadata ( Neither should it be the intent of
W3c ). It should be sufficient to say the metadata should be expressible.

Sateesh

It came from the charter;

"The Working Group will also assess the relationship with the work
conducted in the Semantic Web Activity."

This is a measurable, though weak requirement.  It doesn't require that
we do anything except demonstrate that it's possible.

I'm not sure where the editors got those.  I, as champion, didn't see
them raised.  9.2 seems to be a stronger version of 9.1.  I'm not sure I
like it, for two reasons; one, producing these mappings can be tough.
And two, our work product is a reference architecture, not a particular
technology or set of technologies.
