Re: [soa-rm] Sub Comittee and/or User guide

[Matthew MacKenzie <mattm@adobe.com>]

Duane,

This is exactly how I see things going, having sub committees formed to 
work on reference architectures. One thing I *do* want to be careful 
of, however, is commissioning any of these committees before the 
reference model is at least a committee specification.  I do not want 
to split the TC's attention this early in the process, and I want to 
make sure that the subcommittees are towing the SOA-RM "party 
line"...which is impossible when the party platform is still in 
incubation.

Thanks,
Matt
