WSDL Versioning

Hi,

Could someone please help me with the following WSDL versioning
question?

What is the current status of these WSDL requirements?

The description language MUST allow identifying versions of Services. (From PF. Last discussed 12 April 2002.)
R119 
The description language MUST allow identifying versions of descriptions. (>From PF. Last discussed 12 April 2002.)

Thanks,

Jose Airton.
