RE: What does WCAG mean by "a set of Web units"

I think the third definition in Loretta's list might work:
 
<blockquote>
-       the contents of the conformance statement
</blockquote>
 
The others have problems: "Web site" is the term we were trying to stay
away from in the first place because it's so loose and baggy. The notion
of a set of Web units "intended by an author to be used together" begs
the question of how we test for intention, and even if we figured that
out we might be stuck with the idea of "an author," a notion that much
current Web practice simply ignores: authorship is corporate and
multiple, and many individuals contribute Web content without any
knowledge of the context in which it will appear (this is one of the
reasons we had to wrestle with aggregated content when describing
conformance claims).                I think the final bullet, about all
the Web units that appear in a graph starting from a given point, raises
similar concerns, though it *might* work (is there a way to test out the
idea of such a graph? Or have I  misread the item?

	A number of our success criteria involve properties of a Web
unit within a set of Web units:

	

	2.4.1 A mechanism is available to bypass blocks of content that
are repeated on multiple Web units.

	2.4.2 More than one way is available to locate content within a
set of Web units where content is not the result of, or a step in, a
process or task.

	2.4.7 Information about the user's location within a set of Web
units is available.

	3.2.3 Navigational mechanisms that are repeated on multiple Web
units within a set of Web units occur in the same relative order each
time they are repeated, unless a change is initiated by the user.

	3.2.4 Components that have the same functionality within a set
of Web units are identified consistently.

	We received several comments that point out that the set of Web
units is not well defined, and that these SC can be satisfied trivially
if the "set of Web units" is just the Web unit itself. What "set of Web
units" should an author be considering so that we gain the accessibility
benefits of these SC? Clearly the entire web is too large and the Web
unit itself is too small. 

	

	We started a discussion at the end of today's call about what we
mean, in these SC, by a set of Web units. Some of the ideas that were
discussed included:

	-       the web site

	-       the contents of the conformance statement

	-       a set of Web units that is intended by its author to be
used together

	-       all of the Web units within a site that can be reached
from the graph starting at some root Web unit.

		

	More thoughts or suggestions?
