I have a half-written detailed proposal for gradients.  They're not
quite as simple as you might think, though.

This is possible with the ::marker pseudo-element in css3-lists /
css3-content, for example:

ul.checklist li::marker { content: "✔"; }

In CSS3 (using a proposal that's been around for quite a while) this is
done with:

@namespace xml url("http://www.w3.org/XML/1998/namespace");
span[xml|lang="fr"] { font-style: italic; }

(However, :lang() often has advantages over attribute selectors, since
it selects on a language inherited from a lang or xml:lang attribute on
an ancestor.)

In a non-namespace-aware implementation, you'd need to use
span[xml\:lang] (escaping the colon with a backslash), but that's
probably a bad idea anyway.

This isn't a CSS issue; it's an HTML one.  Proposing it on this list is
unlikely to do much.
