20041014:XLink attributes vs url attribute

Hi all,

This message from Roland.

PS Roland, you sent this to thredds-dev and it bounced because ...

address@hidden is the open THREDDS list, 
address@hidden is a Unidata internal THREDDS list. 
Obviously, we didn't think about this being a confusing, non-standard 
naming scheme when we created the lists. Sorry for the confusion.
