Yes, the current mix is not optimal.

There are a few things to look out for, but we should be able to
handle them. In particular, when a Function is created from an XML
data file. Then a string in the file corresponds to a particular UFC
dof map, but it needs to correspond to a DofMap. So the file needs to
store which original UFC dof map it is based on and which reordering
is used. Or maybe we can just store the complete map (all the
numbers)?

I'm not sure we'll have time to fix this before the release though.
