That's what I was trying to say above ;) either in a mime.types file (in 
Apache format I think) or through an API.

Sure. 1.1.1 does only bring minor things 
http://java.sun.com/javase/technologies/desktop/javabeans/glasgow/jaf-changes.txt 
so you can stay with that as before.
However we may have to endorse it for Java 6 compatibility like we do 
with StAX, or maybe it's the very same version so we do not need to do 
that either.
FYI a `grep` in Yanel trunk and contributions for '"activation"' says we 
currently use activation-1.1.jar in the "contact-form", "atom" and 
"atom-entry" resource-types.

...should be better than the submitted 
http://bugzilla.wyona.com/cgi-bin/bugzilla/attachment.cgi?id=1136&action=view 
patch which is O(N) where N is the number of registered extensions.
I hope JAI is using some kind of hashmap which would be O(1).

I guess you mean Java 5 compatible, not required! ;)

Check! :)

Nothing I can think of ATM.
