[stupid thunderbird whitespace corruption]

Shouldn't this be something more specific than <text/>?  A <ref 
name=.../> to something that matches valid network names might be more 
appropriate.  Then again, network.rng uses <text/> for the name element, 
so I guess we're okay here.

We repeat this <choice> enough times; maybe it's worth factorizing into 
a macro and using it by <ref> in all three call sites?  Up to you - it's 
not a show-stopper to the patch as-is.

ACK.
