Hi Chris:

I had a quick look at the file you sent.

It looks to me like the XML is redundant info to whats in the file (see below). 
I was hoping it would allow me to add shared dimensions, as in the 
StructMetadata of HDF-EOS files. 

It looks like im missing getting a whole bunch of the data inside. ill 
investigate more.
