Fair enough, adjacent features would be an extension and so not affect  
the core spec. As you know a similar adjacent_feature proposal has  
been posted before to the list and yes we should definitely come up  
with a solution now.
I'd say if we don't have any more objections in the next couple of  
days then go with your proposal as is? I'll then put support into the  
registry this week if that is the case. If you could also then copy  
the proposal from here https://github.com/dasmoth/dalliance/wiki/AdjacentFeatures 
  to the extensions page here:
http://www.biodas.org/wiki/DAS1.6E#Adjacent_Feature_filter noting in  
large letters that it was agreed by the community on such a such a date?
