Yes indeed!

5)  <supports value="false"> ... </supports>

1:  I like it because it does what it says.  Setting is something that
can't be changed, as opposed to a default.  It just happens that this
particular setting is a boolean, but it's (extremely unlikely) possible it
could be a numeric setting.

2:  Would rather have an attribute on supports that gives the truth value,
and the default for it would be true.  But this doesn't fix the numeric
issue for things which are set, rather than not supported at all.

3:  Urgh.  We'd need to completely enumerate all the possibilities. ZeeRex
files would become Very long.

4: =)

Yes.  Though it'll need to wait for Ray to get back to actually update it.
