The Web Services Description Working Group uses Z notation 
to formalise the WSDL specification, see:

http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl20/wsdl20-z.html#znotation

In essence this is something of a new adventure for the W3C, owes much
to the work of Arthur Ryman (IBM), and should provide valuable experience 
from which other Working Groups may learn.

As said during the workshop, I question the value of applying formalisation 
after the event, given so much of its value seems to be in finding bugs and 
inconsistencies at a point in time when they can be easily be fixed.

However, I am interested in the potential application of a formal model in 
generating and assessing the coverage of test cases.
