Actually, after a little break from the discussion, I see now that this 
is not necessarily true.  ISO 8601 supports a wide variety of dates.  
They would only be directly sortable if every ogg in question used the 
very same variation of ISO 8601.  So, a stricter format would be 
required, such as the one at the W3C site that Ben linked.

Second, sorting is not trivial if more than one date is associated with 
a file.

Third (I keep adding as I go along :), because DATE can have further 
information, you have to be careful if sorting by additional fields.  
The date portion would need to be extracted before using it as a basis 
for a sort.  For example, to sort by date then performer, any 
descriptive date information would skew the sort, because it has 
precedence over performer.  Instead, the date would have to be 
extracted first - supposing the user *didn't* want the sort to include 
the extra DATE information.
