It is not bad at all, but you can hardly find it system-wide.  AFAIK
there is no standard in packaging such standalone single files
anywhere yet (see also, e.g., JavaScript libraries, everything is
usually bundled).  Once there is a wide-spread standard (if ever)
where such files are located within the distributions, relaxng.rng
can be dropped and dependency can be added.

I share the same intention, however current situation does not seem
to be offering any other choice.
