Please excuse my error. Generated content _is displayed_ for LEGEND element. I've removed it from the testcase URL.

For input this is definitely invalid and for textarea it's probably invalid; for fieldset it's probably valid, though.

Excuse me, but why do you considered it as invalid? INPUT and TEXTAREA are inline replaced elements just like IMG, so, IMO, generated content could be added in a similar way.

It's invalid for IMG too.  The incorrect examples in REC-CSS2 have been removed in CSS 2.1.

My fool error. I've founded what you are talking about. I must read specs more closely.

About textarea, isn't it similar to the button element? Both are replaced non empty elements but button does allow generated content.

The BUTTON element allows child elements so you can also have generated content as child elements...

TEXTAREA is like INPUT.

A bit off topic: So, if that's the rule, I guess generated content should not be allowed for HR element.

<hr> is not a replaced element in Gecko...

Here is one reftest for this bug. Feel free to change it before it's checked in. I guess we should probably get more coverage with some tests that have an element in the <fieldset> and using :before and :after...
