It will make the simple things -- signature validation, for example --
much more likely to "just work."  I do not have a lot of experience with a
wide variety of WS-Security toolkits (some folks consider us competition
:), but I have seen some that assume that *all* security work is in the
WS-Security header.

It will *not* make the trust issues -- the thing I mentioned as the "key
paragraph" automatic.

I don't know of any toolkit that "just does this."  I'm not sure
it's possible.  Even if there were, however, I think it's worthwhile
for this WG to understand some of the issues involved, as most of the
people here aren't actively involved in that part of things, as far as
I can tell.

At the risk of hubris, I'd really like to see what I wrote become
the basis of something official that comes out of this WG.
