a `<figure>` in a `<list rend="ugly">` is rendered in HTML with class="figure ugly"

[sydb]

When an input tei:list/tei:item/tei:figure is run through teitohtml the output is an <html:figure> which has a @class of both "figure" (which is redundant, but not a problem) and the value of the ancestor <list>’s @rend (which seems at least weird, if not problematic).

When an input tei:list/tei:item/tei:p/tei:emph/tei:figure is run through teitohtml the output is an <html:span> (probably because <html:fiugre> is not permitted in <html:p>, but I have not checked) which has a @class of "figure figure" (which is redundant, but not necessarily a problem).

I will attach a tiny little test TEI document that can be used to demonstrate this behavior to a subsequent comment on this issue.

Side question: Might it not be better if TEI element names converted to HTML/CSS class values with a prefix e.g. tei_figure in this case? But I recognise that is a more general teitohtml stylesheet-wide and that prefix would need to be a global variable or parameter.
