A couple of comments on SVG2 Accessibility API Mappings

Hi,

some early comments on  
http://rawgit.com/w3c/aria/master/svg-aam/svg-aam.html.

== Intro section -  
http://rawgit.com/w3c/aria/master/svg-aam/svg-aam.html#intro ==

> "Unlike earlier versions of SVG, SVG2 also closely aligns with the DOM  
> Level 3 Core and HTML5 events to facilitate JavaScript use."

I would suggest dropping the first half of this sentence. SVG Tiny 1.2 did  
require a subset of DOM Level 3 Core. SVG has supported JavaScript  
(ECMAScript) since version 1.0, so it's not new in SVG2 (which seems to be  
implied).

> "With SVG2, authors will now be able to produce rich ineractive charts,  
> and drawings while be accessible to a much broader range of users  
> allowing the author to dynamically supply their intended semantics  
> through through the use of WAI-ARIA."

*interactive. This also seems to imply that rich interactive charts is  
something new in SVG2, where really it's the a11y that's being improved  
here. Would it be possible for this section to convey that message in a  
better way?


== Mapping WAI-ARIA to Accessibility APIs -  
http://rawgit.com/w3c/aria/master/svg-aam/svg-aam.html#mapping_conflicts ==

> "SVG user agents must conform to Conflicts between native markup  
> semantics and WAI-ARIA in [CORE-AAM] where the host language is [SVG2]."

Not sure if it's an important distinction to make here, but svg UA's thus  
far have tended to not care about which specific version of SVG was used  
for the markup, and svg2 has even removed the 'version' attribute on <svg>.

Should this just say "SVG" instead of "SVG2"? I assume the intent is that  
svg-aam should still apply to e.g SVG3.


== SVG2 Element Mapping Table -  
http://rawgit.com/w3c/aria/master/svg-aam/svg-aam.html#mapping_role_table  
==

feCustom has been dropped from the Filter Effects spec, suggest removing  
it here too. See http://www.w3.org/TR/filter-effects/#changes.
