The haudio proposal does say
"The type of the file /MAY/ be specified by using the |type| specifier
for a URI."
http://microformats.org/wiki/haudio#Full_Download_.28Enclosure.29
Maybe this can be changed to:
"The type of the file SHOULD be specified by using the type specifier
for a URI."
Maybe may encorage more haudio publishers to use the type="" specifier,
Its also good to note that once haudio eventually becomes more stable
we can then start adding extra pages such as hAudio Parsing and hAudio
Authoring.
