About your second inquiry: I'm not sure what you mean by "link" in this 
context. In XDMF, a column or row of a HDF matrix can be accessed using 
the HyperSlab dataitem with a count value of one. You can then use an 
XPath reference to attach a name tag to that subset of your matrix. A 
more specific example of what you're trying to do might be helpful here.

Best, Jens.
