Unprefixed attributes on elements in the SVG namespace must not be
used for extensions.

But that's exactly what WAI-ARIA asks host languages to allow; that
the aria-foo attributes appear un-prefixed:

<quote
cite="http://www.w3.org/WAI/PF/aria/#host_general_property">

The names of these attributes do not have a prefix set off by a
colon; in the terms of Namespaces they are "unprefixed attribute names."

</quote>

(Read at least the whole linked paragraph.)

When I ran our approach through the Hypertext CG, I believe the
feedback I got was that your group had reviewed this and were willing
to live with the un-prefixed, aria-foo attribute names for the WAI-
ARIA states and properties.

So I hope that this is just a matter of incomplete editing, not a
latent disagreement about the host language embedding approach for ARIA.

** proposed change TBD

This is rough, but one possible way to fix this would be to add a
section 18.5 to the Metadata chapter that reserves attribute names
that match the pattern aria-* for use as specified in the [work in
progress] WAI-ARIA specification. And allows their presence on
elements from the SVG namespace. Then chapter 19 can say "except as
provided in 18.5, unprefixed attributes on elements in the SVG
namespace must not be used for extensions."

This prose would be backed in the schema by a loophole in the syntax
that would accept zero or more attributes with names matching this
pattern on any SVG element. We would do actual checking to an
experimental schema that would be generated from the spec draft,
until the WAI-ARIA spec completes the Rec track. This RNG
(optionally plus Schematron) schema could resemble the example
discussed at
