First, many thanks. It is good to have some wording to ground this
discussion. here 
are my specific points/questions.


1) publish vs. advertise
	For many reasons[1] I prefer advertise. Can we change?

	[1]
http://lists.w3.org/Archives/Public/www-ws-arch/2002Oct/0037.html


2) Description
	a) In section 1.2 you state: "A web service is described using a
standard, formal XML notation..."
	Could it not also be described over the phone using Greek, Latin or
English? 

	Later on you use "may be realized as a set of XML description
documents" This seems 
	more accurate.

	b) Later in the paragraph you state: "provides all of the details
necessary to interact with the service..."
	Not really. It can not describe pre and post-conditions, the
business or legal context etc.
	It seems worth while to break description down into at least three
pieces: concrete, abstract and
	service level where WSDL can provide concrete and abstract
description data. 

	c) In "Artifacts of a Web Service" the last sentenance of the web
services description bullet says
	that a "description may be published to requestor directly or a
discovery agency".

	Do we want to say that or do we want to say that at times the
requestor acts as the discovery agency
	and requests the description directly? This says that even though
the exchange is direct, there is
	still a distinction of roles.
	

3) Discover Services
	I like this term. In fact, I think having it plural makes the need
to incorporate advertising/publishing 
	clear enough. 

	But, in the section "Roles in a Web Service Architecture" you switch
to "Service Discovery Agency"
	The text works for me, the term used is singular and different than
the graphic.

Regards,
DaveH
