A new element would work, if it was defined as > the caption of a <figure>. We should perhaps have had a systematic evaluation of the advantages of new vs old element? For IE, the advantages of a _new_ element is that, via JavaScript, it becomes an XML-like element, that closes with the end tag. Whereas when resusing <dt> and <dd> is used inside <figure>, then in IE version 6 and 7, they will swallow the the subsequent element - disregarding the closing </dd> of </dt> or </figure>. http://software.hixie.ch/utilities/js/live-dom-viewer/saved/235 So, for IE 6 and 7 compatibility, there is an advantage to using new elements - instead of reusing <dt> and <dd> in a new element. > A third solution (that was actually suggested by you, Lachlan, > yesterday in IRC) is to use an attribute to disambiguate the caption > from the content. So you'd have markup like: > > <figure> > <p caption>Exhibit A</p> > <h1>Madonna and child</h1> > <img src="foo" alt="bar"> > </figure> As Lachlan said, one disadvantage to this would be that it would be impossible to place the caption /last/. Unless you also add a special rule for last child ... Also, if you can accept <figure caption >, then why not <dl figure > instead? -- leif halvard silli
