Since we don't particularly want to allow extraneous text before <legend>, I
fail to see how.

The claim that it "_already_ works" seems plausible but would need to be
verified by demonstrating that <legend> elements wrapped in or preceded by
other elements are still correctly associated with their ancestor <fieldset>
elements when HTML documents are represented to the accessibility APIs used by
assistive technology and by current AT using those APIs or the DOM.

In the past, there have often been bugs in the plumbing that makes
accessibility work, even for markup that follows the standard. For example:

Also, just because something already works now does not mean it's the best
design long term.

With respect to simply _wrapping_ legend for the purpose of styling it, can you
please point to a design that you think cannot be implemented in HTML5 and CSS3
as currently proposed, rather than test cases that include extraneous text like
the ones you linked to?

You haven't given any rationale at all for allowing elements to precede rather
than enclose <legend>. If you're *not* proposing to place elements with text
before <legend> what do you want these preceding elements for? Why could you
not wrap the whole <fieldset> in a <div> and place those preliminary elements
outside the <fieldset>?
