It's not informative, it's delayed :) I.e., it's not an informative 
part of a Recommendation, it's a note to try to get something down with 
a recommendation of future standardization.

Exactly. Plus an acknowleding that even with a 2 year extension, the 
WSDL working group just doesn't have the resources to deal with it. 
It's not like there is, to my knowledge, *any* existing practice for 
this sort of description in WSDL. There is a fair bit of work at the 
Semantic Web service level, especially for distinguishing "safe" (in 
some sense) from world altering processes, but this isn't tied at all 
to web architecture as would, in my mind, provide sufficient experience 
to ground standardizatin.

So, a working group note should provide enough of a hook for the 
community to hang a hat on, and a basis for future standardization.

WSDL 2.0 is strongly oriented toward extensibility. We've already 
shoved a fair bit into the core spec :) The group is trying to be 
careful not to include things that implementors just won't implement.

Cheers,
