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


<SOURCES>
<SOURCE id="DS2_1" title="yeastdas2server1"  
doc_href="http://cvs.biodas.org/cgi-bin/viewcvs/viewcvs.cgi/das/das2/ 
new_spec.txt?rev=1.6&cvsroot=biodas&content-type=text/vnd.viewcvs- 
markup">
−
	<VERSION id="latest" created="2006-02-08">
	<MAINTAINER email="allenday at ucla.edu"/>
−
	<COORDINATES taxid="4932" source="Chromosome" authority="SGD"  
test_range="chrVII/364251:366080">
	<VERSION name="32"/>
	</COORDINATES>
	<CAPABILITY type="segments"

</SOURCE>

	</VERSION>
</SOURCE>
</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



Cheers,
