Part of Item: 
Comment Type: technical
Comment (Including rationale for any proposed change):
This is a follow-up regarding my earlier comment concerning \"not embedded in

another resource\" (part of the definition of \"Web page\").

The scenarios I outlined can only occur where the same resource is within the

scope of two distinct conformance claims. Having considered this furhter, I

think it\'s reasonable to propose the following solution.

Proposed Change:
\"Not embeded in another resource\" means \"not embedded in another resource

covered by the same conformance claim\", or wording to that effect.

Note that if I place a resource (e.g., an image) on my Web site, make a

conformance claim applicable to the whole site, and reference the image only

in a link, without embedding it in any of my other resources, then the image

will count as an independent Web page, and will be subject to all of the WCAG

2.0 conformance requirements at my chosen conformance level, even if the link

text provides a text alternative. A resource that is linked to cannot be

regarded as embedded, otherwise many resources that should count as Web pages

would fail the definition simply in virtue of being linked to by other

resources within the scope of the conformance claim. I think these

consequences of the current definition, which are not affected by my proposal

above, are tolerable; but it does appear that if a content author has a

collection of images and refers to them only in links, it will be necessary

for example to wrap each image in an HTML page to prevent it from being an

independent Web page under the definition.
