Eh...filters are filters. I'm no fan but it doesn't seem to be nearly 
as bad as he made it out to be. In fact, some of the criticism is 
downright silly. E.g.:

"While these documents might be useful to someone developing a WSDL 
tool, they are practically useless for a web services developer who 
wants to use WSDL to define their interface."

The wg made an explicit decision to make the *specs* targeted at 
implementers. There is to be, in current W3C tradition, a *primer* 
which is targeted more at users.

More non, again. I mean, the only one that really seems to matter is 
the last (i.e,. is a real technical objection). The rest seem mroe 
taste based (he doesn't like the generality). Eh.

I don't know about that. But it would be possible to make one 
consistent. Indeed, I believe you could compile WSDL 1.1 to the WSDL 
2.0 component model, which would give you URIs. I'll investigate.

Tell them to go away :)

Seriously. The *only* reason to stay with DAML+OIL is for qualified 
number restrictions and it would be better for some sensible folks to 
simply define an owl relevant extension for them.

Verra true.
