[Heh-heh. I've been expecting this question ... :-]
I think the answer is yes, you *can* encode a pointer to an audio
file using <graphic>. There are three problems, though.
1) The tactical semantics are incorrect. Even though to a casual
reader it is clear that
refers to an audio file, the Guidelines clearly state that
<graphic> is for "an inline graphic, illustration, or figure".
2) The attributes are incorrect. <graphic> has, e.g., height= and
width=, but does not have dur=.
3) The strategic semantics are probably incorrect. I'm not sure of
your situation, but remember that the TEI is primarily about
encoding extant texts. (Which is not to say we don't use it for
born-digital stuff, we do.) So the <graphic> element is primarily
intended to represent a graphic that exists in an existing
physical document. (E.g.,
http://www.sffaudio.com/images08/flatland500.jpg.) So if what
you're doing is adding a pointer to something else, e.g., to an
audio instantiation of the current document, or a commentary on
it, then encoding with <figure> and <graphic> may not be the right
thing to do anyway.
In any case, I'd recommend either:
A) Using <ptr>:
B) Customizing TEI as to create a new <my:audio> element that is much
like <graphic>, but has correct semantics and attrs.
Other possibilities (which I'm not as fond of) are to abuse the
<graphic> element or the facs= attribute.
