This is not possible with the XML formats.  You could look at HDF5 to do 
that (which ParaView can read), but I do not know too much about it.

This sounds like an interesting idea.  I do not know how hard it is to 
implement, but please at least add it as a feature request to the Bug 
tracker:

so it will be investigated at some point.
