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.
