RE: GUIDE: Re: WSCL "well-formerdness" concept

Hi Jim,

I agree with you, this is very relevant. I started looking at the document.
It will be interesting to compare it with WSCL, BPML, XLang and WSFL. For
now, I see little difference between all of them.

GUIDE focus group - the WSCL submissions relates to both our agents 
and services use cases and discussions - might be furtile ground for 
some test cases.  I hope you will consider reading this and thnking 
about generating some examples based on it - would be a nice tie of 
our work to Web Services in an emerging area of interest.
