While designing a policy assertion (issue 6403) for WS-Enumeration, we (Doug,
Katy, Paul, Ram and I) bumped into a question. What does it mean to say that a
Web Service indicates the use of WS-Enumeration? We found the following text in
WS-Enumeration [1] to answer the question: 

�All data sources MUST support some operation that allows an enumeration to be
started. A data source MAY support the Enumerate operation, or it may provide
some other mechanism for starting an enumeration and receiving an enumeration
context.� 

The quoted text is a bit vague though, particularly the phrase 'some
operation'. We think that the quoted text could be clarified and made crisper.
Here is a proposed replacement text: 

"Data sources MUST support the Enumerate operation to start an enumeration. A
data source MAY provide other mechanisms for starting an enumeration and
receiving an enumeration context."
