[DDI-SRG] Single child Reference element in referenecs

[Pascal Heus]

Achim, I-Lin:
we reviewed yesterday bug #2 
(http://mantis.ddialliance.org/view.php?id=2) related to the extra 
*/Reference element that appears under every referencing type in the 
current schema. We had a general agreement that this is not necessary 
and that it should be removed or possibly replaced with a fixed 
@isReference attribute. Since I believe you initially requested this 
change, we would like to have your perspective on the issue before 
making a final decision.
Would appreciate your prompt input as this change impacts most of the 
ongoing tool development and the earlier we can make it happen, the better.
many thanks
Pascal
