Actually, let me expand a little on this...
What I disliked about opt 2 is that it seemed like
we were making axis deal with what I could call
a provider specific element.  Opt 3 avoided that.
Going the Ant approach would definitely be
preferable over option 2 and could get Axis
out of that business forever.  Very appealing...

yup - it can go either way.  it depends on how much
work you want to make new provider writers to do.
I can see advantages in both.

I'm a fan of schemas that express the semantics in a rich and verifiable

There are ways of implementing this in a general manner.  One such way is
the way that Ant introspects tasks - simply define setters for every
attribute  in which the specific service simply defines setters for the
attributes it wants to accept.  Or the services can provide descriptors
(this is the approach Excalibur takes to options).
