Yep, no problem whatsoever.  :)

I assume that you're willing to license this as GPLv3 ?

Reinhold is the musicxml2ly guy.  More regression tests are
welcome, as long as they're placed in the public domain or are
licensed under GPLv3+ or GNU FDL 1.3+.

Please send a patch which adds the files to
input/regression/musicxml/

Help for patches and devel and whatnot is here:

Thanks for the offer!  I think lilypond.org is fine at the moment,
but the Mutopia guys might like another mirror.
