I think http://www.w3.org/Bugs/Public/show_bug.cgi?id=10901 should
remain as WONTFIX.

 * We have interop between Gecko, WebKit, Trident (since IE9 on this
point) and Presto (once Ragnarök ships). Hooray! Interop is hard. When
it has been achieved, we shouldn't self-sabotage it.

 * Even if we considered the replacement cycles of Firefox and Chrome
to be fast enough that Firefox or Chrome legacy didn't matter,
Microsoft has deployed XML-style tokenization of SVG in IE. (Apple has
deployed the parsing in Safari, too.) Microsoft says IE9 will be
supported until January 2020. Even if IE9 doesn't have a large active
userbase all the way until 2020, I think authors who try to make Web
content that works would be worse of if we had a period of even a
couple of years with browsers that support SVG-in-text/html tokenizing
script&style content substantially differently. (Which would be the
case if we changed the tokenization but MS didn't agree to issue such
a drastic change as a patch for IE9.)

 * If we changed SVG style to tokenize like HTML style, we'd most
likely end up breaking the kind of copy&paste scenarios that the SVG
WG really wanted to work in the first place. (This argument also
applies to script, but style is even more likely to occur in the kind
of content one would expect to be able to copy&paste and have it just
work.) Maybe the SVG WG has changed their mind now, but we shouldn't
let them flipflop now that we've reached interop.

This ship has sailed.
