Hm I see this as a possibility but what about the following:


<SOURCES>

This would be how to write one server which has two coordinate systems.  
according to the "one coord sys/server" rule.
I think it would be shorter to provide two coordinates sections for  
that and only one source description...



--- fyi, a yeast by Gene_ID server is  e.g.
http://das.sanger.ac.uk/registry/showdetails.jsp?auto_id=DS_169
