Better: (gnu packages xml).

So java-cup has a dependency on itself via jflex?
Please add FIXME here, so that we can fix this once xalan is packaged.

I still don’t know where “jaxen-no-rec-deps” comes from.

Why?

I prefer not to use string-append here.  You can split strings and let
them span multiple lines by escaping the line break.

Please remember to rename this when renaming “java-jaxen-no-rec-deps” to
“java-jaxen-bootstrap”.

That’s a bit short.  Could you elaborate?

Weird license :)
