RE: XMLP Review of WSDL 2.0 Part 2 LC WD

Thank you for the comments below, and for your patience with us in
resolving them.  In summary, we accepted all of your comments and have
implemented the fixes in the latest draft [1].  See below for further
details on each issue.

If you agree with our disposition of your comments, we'd like you to
acknowledge it within two weeks; otherwise we will assume you are
satisfied.  The WG plans to enter a second (short) Last Call period in
the near future, and we invite you to review that publication as well.

We tracked the comment above as Issue LC48a [2].  The editors have
resolved it as you suggest, and carried spirit of the fix through the
name change of the Part 2 document and its merge with Part 3.

We tracked the comment above as Issue LC48b [3].  The editors have
resolved it by referencing new sections describing the mapping in
greater detail.

We tracked the comment above as Issue LC48c [3].  The editors have
resolved it as you suggest.

We tracked the comment above as Issue LC48c [4].  The AD feature has
been substantially redesigned, and the functionality is now provided by
a soap:header element in the SOAP Binding [5].  The comment has thus
become moot.
