No, you would not, except as provided by some copyright license with
TEI's copyright owners. As I posted before, the right to make
derivative works is a component part of the bundle of rights that
the copyright owner has.

Correct. However, if the algorithm were patented (which it is not),
you would have other problems.

It's only the other fella's lawyers who will have a field day.
Your lawyer will tell you to settle, and quick. Running a2p
over a document is just like translating it into French --- you
can't distribute the result without a license.
BTW, these are all international (i.e. Berne convention) rules,
not local law.
