I've started looking at this. If Vector and Mesh have input/output,
then a Function should just have to write those two in the same file
(alternatively store filenames of a vector and a mesh). We should make
all the DOLFIN XML io functions write XML fragments only (i.e. skip
the header), then we can reuse them in the way I've described. I'll
work on this tomorrow.

We can assume the incoming file is a valid DOLFIN XML file (by Schema
validation). The schema doesn't exist yet, but it will eventually..
