I just remember that XPath was pretty big on creating Attr nodes from
attributes, which is why I had to optimize that code path. If anything breaks,
tests will tell.

I'm not sure how what Firefox has to do with this - it's just an implementation
detail of XPath, it can certainly be special-cased to use custom attribute
values instead of Attr nodes internally.
