Hi Ian,

I'm getting deja vu here. I can't keep track of all the discussions
I'm in with you, in which you dismiss someone else's view as providing
'little or no benefit to the author', or assert that XML technologies
are unused on the web. Are you really serious when you say that XPath
is an untested technology? I had to look twice at the date...I'm sure
you must be having a little jest.

Anyway, the request for XPath selector support *is* actually being
made by authors and application builders, and I think it would be wise
to design XBL in such a way that the binding *selection* process is
distinct from what the bindings actually do. If an implementer chooses
to only support CSS selectors then that's fine, and doesn't bother me
at all.

One last thing; simply repeating endlessly that XPath selectors are
sub-optimal doesn't make it true. But I actually don't see it as
relevant to the discussion, one way or the other. It's up to
implementers--standards writers should provide the choice.

Regards,

Mark
