Eric, the issue in the synapse configuration language is that you do not have a section which declares the sequences to do this, sequences, endpoints, proxies and all local entries are on the same XML depth and there is no chance to specify this configuraiton as you explained. If we had a <sequences> tag enclosing all the sequence definitions, this would have been the ideal approach, but it is not the case :-(
My bad - you are right. Sequences can also be defined in different places, including inline in proxies etc. I should have looked at the actual configuration - it looked different in my memories. ;-)
