<pre>What is the use for differentiating those sub-types? Apart from &quot;correctness&quot;.

If we had different applications handling them, or the applications used only
shared-mime-info to differentiate the different types, then it would be a good
reason to split them up. Otherwise we'd just add the sub-types as aliases for
the jp2 format, and be done with it.</pre>
