Glyn et al:

I'm all for clean architecture, and lord knows we went through several phases
of trying to do this during the project.  As various new people have come on
and left, we've lacked some common mental models of how things should work,
which has in part resulted in a less than completely modular/elegant system
design (though frankly I don't think what's there is really that bad, except in
certain areas).

I really don't want to get down on you for being psyched about doing good
stuff, Glyn, but I also think that this kind of message at this stage of
development sort of contributes to the problems we've been having about team
cohesion and timing.  I really wish we could all pull together as a team and
get 1.0 out the door, rather than going off in different directions pulling
things into new shapes.  It feels like we're all "Axis committers" working on 3
different projects and that is extremely uncomfortable for me.

Related to this, I've also been sort of disappointed that people are putting in
time to do all this refactoring and redesign on areas that (IMHO of course) do
nothing for Axis' core functionality and getting 1.0 finished and out the door
so we can start on the next version, when all of this becomes, I think,
appropriate and encouraged.

I think:

- Bug fixing / interop is critical.
- JAX-RPC compliance is critical.
- TCK compliance is critical.
- SOAP 1.2 compliance is slightly less important, but still critical.
- Performance and ease of use are also in the fairly critical category, IMHO.

I don't see much else (i.e. refactoring, code cleanup, etc) as being that
critical right now, to tell you the truth.

I guess I'm saying that I wish we could all spend our valuable brain and
keyboard time doing 1.0-related things rather than branching off in new
directions.  Naturally, this is just my opinion and you should do what you feel
is right.

I'm sorry if this is less than perfectly written, I'm in the midst of a working
group discussion while typing...
