Upgrade wording throughout in response to hixie's comments about providing
better hooks for HTML5 and more normative wording.
<Hixie> fantasai: how should HTML5 refer to
http://dev.w3.org/csswg/css-style-attr/ ?
<Hixie> there doesn't seem to be a "hook" defined that I can use
<Hixie> e.g. i'd like to say "the style attribute is a CSS Styling Attribute.
[CSSSTYLE]" or something
<Hixie> where "CSS Styling Attribute" would be some term of art defined in that
draft
<Hixie> it also seems to be lacking in normative conformance criteria
<Hixie> for example, it doesn't seem to include the equivalent of this
requirement in html5:
<Hixie> "In user agents that support CSS, the attribute's value must be parsed
when the attribute is added or has its value changed, with its value
treated as the body (the part inside the curly brackets) of a declaration
block in a rule whose selector matches just the element on which the
attribute is set. All URLs in the value must be resolved relative to the
element when the attribute is parsed."
<Hixie> (the latter bit is required to handle changing base URIs, e.g.)
(will handle the last line in the next commit)
