** Comment/Recommendation: Request further clarification from UAAG. **


- (DAC-1)  The user has the ability to have indicators rendered along with
rendered elements that have alternative content (e.g. visual icons
rendered in proximity of content which has short text alternatives, long
descriptions, or captions).

		 An example of this is necessary for clarification


- (DAC-1)  In cases where the alternative content has different dimensions
than the original content, the user has the option to specify how the
layout/reflow of the document should be handled.

	Requires clarification - how does this relate to media?  Is this
not an authoring issue?


- (DAC-2) The user has a global option to specify which types of
alternative content by default.
	
	Agreed

	. and, in cases where the alternative content has different
dimensions than the original content, how the layout/reflow of the
document should be handled

	Requires clarification.  Is this not an authoring issue? How does
this impact on media (<Video>) which is not a 'document'?



-	(DAC-4) - Recommendation is to be removed, as it is redundant and
addressed elsewhere in the requirements document.

-	(DAC-5) - This is the same recommendation/requirement that the
User Agent already has for images.

-	(DAC-6) - Q: Does "cascade" refer to the same kind of list that is
configurable for Content-Language?  A: Yes

-	(DAC-7) - This capability will exist as part of the alternate
content selection controls.

-	(DAC-8)- Recommendation: Re-word this to say that "User Agents
must present a User preference/control to disable auto-play".
