Norm describes the issue of "caption" in HTML tables and
his move to
make caption mixed content to support it.
Proposed: this is the best solution to a complex problem so that's
what we'll do.
Does "mixed content" refer to a mix of HTML elements and text or to a
mix of HTML elements, text, and DocBook elements?
Mixed inline and block elements. The problem was that the HTML <caption/>
element contained inlines and the DocBook <caption/> element (valid in
<mediaobject/>) contained block elements.
