[PATCH] docs: Document camelCase preference for XML elements and attributes

[Michal Privoznik]

Recently I've merged a patch that used hyphens in an attribute
name. I fixed it later, but turned out we don't document our
preference which is camelCase.

I'm not sure this is the correct place to put this, suggestions welcome.

+      Please note that single word names for attributes and elements is
+      preferred. But if you have to use two ore more words please join them in
+      camelCase style.

       This task is in many ways the most important to get right, since once
       the API has been committed to the repository, it's libvirt's policy
