[THREDDS #EFD-558110]: HDF5 (nested variable name) + NCML



Hi Abdelrezzak,

I tried your NcML in ToolsUI and caught a couple of exceptions mentioning the 
datatype attribute.  I'll need to look into this and see if what you are 
proposing is something we actually should be handling, or if we just need a 
nicer error message to convey the fact that we can't do what you're trying to 
do.
