I plan to package the W3C's Java bindings for DOM <http://www.w3.org/TR/REC-DOM -Level-1/java-language-binding.html>. The recent versions of my XT package needs it, so either I package it, or "potato" is released without a XSL tool, which will be a problem in the XML "market".
No technical problems expected, they compile fine with jikes and mmake produces a much better Makefile than the braindead one which is shipped upstream. A legal problem occurs since these bindings are regarded by the W3C as a specification, not as a program and are therefore non-free (no modification allowed). Discussion on debian-legal, please, but Cc:, I'm not on this list.
