Bug 10981 - Is there reasoning behind <summary> not being able to contain headings? I can see a lot of real-world uses for that that I'd love to do without JS. For example, take the "Edit Description" H2 in this mockup: http://people.mozilla.com/~chowse/drop/sumo/kb/

Is there reasoning behind <summary> not being able to contain headings? I can
see a lot of real-world uses for that that I'd love to do without JS. For
example, take the "Edit Description" H2 in this mockup:

Status: Rejected
Change Description: no spec change
Rationale: It's not so much that it can't contain headings, so much as it has to only contain phrasing content, much like <legend> or <p>, or, indeed, <h1>. 

In the example given, you can just use <details> as is. Just style it to look like in the mockup using CSS. It's all semantically fine, because the whole point of <summary> is that it's the "heading" for the contents of the <details>. :-)

(It's a little suboptimal in that really <details> should be used to hide stuff that is summarised in <summary>, not to create a section that can be closed, the latter is really more presentation. But that's somewhat splitting hairs.)
