Flatten an rnc schema?

[Lech Rzedzicki <xchaotic@gmail.com>]

Hi.

I am looking for something that will flatten my RelaxNG schema written
in the compact syntax.
I was really surprised not to have found anything yet, I didn't find
any suitable option in Trang, Oxygen has a "flatten" option but that
only works for xsd.
Worst case is I will convert to XML, run XProc/XSL to resolve the
included files, but like I said, I am really surprised that there
really isn't something out there already (or is my google-fu weak?).
