Here is the current definition of Web Page from WCAG. It sounds
technical but it is interestingly difficult to define accurately. Also,
resources like an image may not be referenced on a site but may be cited by
others. Thus the phrase "scope of conformance" is important so that a site
it not responsible for accessibility of pieces of web pages that are pulled
from the site and posted by others.



The rationale for the other aspects of the term can also be provided if
desired. They will all be in our support document for WCAG "Understanding
WCAG 2.0" as well.




Web page


a non-embedded resource, that is referenced by a URI within the scope of
conformance, plus any other resources that are used in the rendering or
intended to be rendered together with it"

Note: Although any "other resources" would be rendered together with the
primary resource, they would not necessarily be rendered simultaneously with
each other.

Example 1: When you enter http://shopping.example.com/ in your browser you
enter a movie-like interactive shopping environment where you visually move
about a store dragging products off of the shelves around you into a visual
shopping cart in front of you. Clicking on a product causes it to be
demonstrated with a specification sheet floating alongside.

Example 2: A Web resource including all embedded images and media.

Example 3: A Web mail program built using Asynchronous JavaScript and XML
(AJAX). The program lives entirely at http://mail.example.com, but includes
an inbox, a contacts area and a calendar. Links or buttons are provided that
cause the the inbox, contacts, or calendar to display, but do not change the
URL of the page as a whole.

Example 4: A customizable portal site, where users can choose content to
display from a set of different content modules.




Resource


A network data object or service that can be identified by a URI
<http://www.w3.org/TR/di-gloss/#def-uniform-resource-identifier> . Resources
may be available in multiple representations (e.g. multiple languages, data
formats, size, resolutions) or vary in other ways.

(This term was taken verbatim from Hypertext Transfer Protocol --
<http://www.w3.org/TR/di-gloss/#ref-http> HTTP/1.1)
