Adding Contributions from external file?

[Spencer Crissman]

Is it possible to load a contribution from an external file? 

I have some configuration information which I would like to allow the user to edit.  It would be nice if I could tell the user to modify an xml config file, but at the same time not have them working in the hivemodule.xml file. 

Basically, I was hoping for being able to specify in hivemodule.xml:
<contribution configuration-id="whatever" file="/path/to/foo.xml"/>

And then the user can provide just the "foo.xml" at the correct location and it will get picked up as the contribution.

Anyway, obviously that doesn't work as listed, but is there an alternative method to do something similar?  I see nothing vaguely like it in the documentation, but it doesn't seem completely unreasonable to me.

Thanks in advance,

Spencer
