Is redland really needed ?

[Matúš Kukan]

Hi,

It's getting hard to spread gbuild across external libraries and since
it's not clear to me how redland is used, I'd like to ask.
Seems to be needed only for unoxml/Library_unordf.mk
That's small library with com.sun.star.rdf in unordf.component.
git grep 'com\.sun\.star\.rdf' gives results only in
foo/qa/complex/*java files, so it may not be needed ?
But it's worse with git grep 'com.sun.star.rdf' giving results in offapi...

What am I missing ?

Thanks,
Matus
