Comment: Where it states "The broader term was chosen because it covers Web applications and other types of content to which the word "page" may not apply" it gives no example of a "web unit" that is not a "web page".
Proposed Change:
Provide an example of a "web unit" that is not a web page.
We have replaced the term "Web unit" with "Web page" and have modified this section to describe our use of the term in greater detail. We have also added an example of content that may not immediately be recognized as a "Web page."
The definition, found at http://www.w3.org/TR/2007/WD-WCAG20-20070517/#webpagedef , now reads:
Web page
a resource that is referenced by a URI and is not embedded in another resource, 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.
