One other things...
The other important point to that is that the <a> element makes use of
the "type" attribute to show that it points to a video.
(Example MIME types in there that would signify a video are
"video/mpeg", "video/quicktime", etc. One problematic video MIME type
is that of Ogg Theora; which is "application/ogg"... which would
require you to probe the file to see if it contains video or not....
and not just sound or something else.)
Software could them check the Content Type (storted in the <a>'s
"type" attribute) to see if it is one for a video.
NOTE that the <a>'s "type" attribute contains a Content Type (and NOT
just a MIME TYPE). So parsing it might take a bit more effort. Refer
to Section 14.17 of RFC 2616 for more information on content types
