Re: [opencsa-liaison] Reference dependencies in various SCA specs

[Jeff Mischkinsky <jeff.mischkinsky@oracle.com>]

we can also allocate some time in Process Committee if that would be  
desireable/easier.

FWIW I think the problem is that the SCA TCs are not really completely  
independent of each other. (I think of them as "almost separable".)  
When we were first developing SCA we discussed whether we should have  
one big TC or break things up to make development more manageable  
realizing that the trade-off was that we would have mutual dependencies.

That said i'm not sure the real issue is independent TCs. The mutual  
dependencies would exist even if there was one TC. Having multiple TCs  
makes it more complicated because its harder to coordinate  
simultaneous votes on mutually dependent specs across TCs. I'm trying  
to remember why we don't allow DCR's for CSD's. I *think* it might be  
because we thought that since these were "only drafts", it was ok if  
there were some inconsistencies/bugs and not worth the effort to allow  
DCR's.

The suggestion to allow TC's to decide if a change is not "substantive  
enough" is that we were never able to agree on a definition of what  
"enough" meant and TCs will almost always declare a change to be non- 
substantive, regardless.

Actually we already have that issue on the Process Committee's agenda  
as part of figuring out if the requirement of new PRs for any change  
is creating too many PRs.

cheers,
