Krishna,

I would agree with you on the cacheability aspect. I am sure we will have
several
other such scenarios.

Regarding authC, authZ, etc.:

My intent was to be able to communicate that a given *operation* or message
interaction
may require security interactions, and thus authC, authZ etc. make perfect
sense.

Sandeep,

	I would like to add :

	4.	Cachability parameters about the message.

		A simple example is a query web service from a database
which is updated once a day. So the web service output message can be
cached for 24 hrs, or more precisely cached till say 6:00 AM. There
could be other metadata associated with the caching of that message.

	Would it be a better idea to change 1 to :

	1.	Security Information which might be authC, authZ, ...

cheers

 |
 | A WS description allows it to publish the message
 | interactions it is capable
 | of handling. However, this description alone does not
 | capture any meta-information associated with the message interaction
 | definitions. The message interactions are meaningful in a
 | given business domain, or more precisely, as defined as part
 | of W3C work on
 | ontology [1].
 |
 | A Web Service description SHOULD be able to define
 | extensible mechanisms for
 | capturing meta-information associated with a message.
 |
 | Some of the examples of the meta-information are:
 |
 | 1. Some messages of a WS may require authentication information.
 |
 | 2. Some messages of a WS may deal with in a particular
 | Business Domain. For
 | instance, submitPO, may be an overloaded
 | message where one such message primarily deals with RosettaNet.
 |
 | 3. QoS parameters
 |
 | Comments are welcome.
