I have no much problem with this. But what kind of checking are you
suggesting doing. Will a lib for 1.5 mean that it should work with 2.0
(ANT2). My problem with this kind of thing is that in reality the rules are
more complicated than just a min version. Notice that upto now we are keen
on maintaining buildfile compatibility but not as much for code.

No problem if optional, but notice this xml file is kind of buried in the
jar, unless there are GUI tools that access this info, it is not too useful.
And in that case you will probably want something more sofisticated than a

I meant any kind of unique ID for the task. Conor's package naming is fine.

Isn't this what "version" is specifying?

we need version of the manifest file and version of the tasklib.

Unique ID and version should go in from the begininning. If the stuff is in
there you can enum all tasks, find out their names and origins. Or have a
server which retains versions of tasks so you could send a query
and then the server could return the appropriate version of the library.
