Hi, Jonathan-

I don't think it is off-topic (well, okay, sometimes it is :). I just think
that you and I have different views on where these things should be handled.
Perhaps it's good to err on the side of being more careful about
accessibility.

The newest draft has specific language about highlighting [1], and I
wondered why you didn't think it sufficed:
"In SVG 1.2, highlighting in a conforming SVG viewer must be visually
detectable. The default rendering is left application dependent, it just has
to be visible."

This seems very sensible to me, and I'd think it does lay the groundwork for
the kind of functionality you're emphasizing.

Regards-
Doug

| Doug,
| 
| thanks once again for taking the time to try to understand my 
| description of accessibility issues, which can appear to be off-topic.
| 
| W3C publishes a broad range of documents including 
| specifications, there are for instance accessible authoring 
| tools guidelines http://www.w3.org/TR/ATAG10/ though these 
| primarily refer to html tools, they also include such diverse 
| items as quick tips 
| http://www.w3.org/WAI/References/QuickTips/ training 
| http://www.w3.org/WAI/training/ accessibility features of SVG 
| http://www.w3.org/TR/SVG-access/ the test suite and of course 
| all the other useful documents already linked to from the SVG website.
|

| however unless we can identify a more accessible viewer or 
| authoring tool, and believe he was aware of this, the 
| generalisation would still hold true, though I accept it is 
| unlikely he was referring to the spec itself. 
| However in true W3 fashion the spec is not accessible to a 
| wide audience.
| Aaron has expressed interest in the proposed accessibility 
| documentation, "Especially if it gets down to practical details"
| 
| the problem of link highlights being similar to their 
| backgrounds applies equally to html, and can be found in the 
| wild. this issues is many magnitudes of order less frequent 
| than the default, which as we know barely exists for SVG.
| 
| let's hope we can start creating these essential SVG 
| accessibility documents sooner rather than later, and let's 
| ensure these documents are truly accessible to a wider audience.
|
