Hi Alex, 

Still in China, just checking mail from an internet cafe.  To answer your questions, Z segments (if they are not recognized, ie you don't make a custom message), will just be ignored (no exception thrown).  In a couple of months I want to have these parse into generic segment objects so they are there if you need them -- for now if you need to access data from a Z segment you have to make a custom message class.  

Message classes that work with all versions is tricky.  Often the structure changes slightly between versions (eg ST changes to CE).  In the long term there may be a way around this but it is a long way out -- it needs the conformance classes project, which will be complete around April (let me know if you want more details).  For now if you want to switch HL7 versions you have to make code changes.  It sounds like a pain but in my experience it only takes a few minutes (just try to compile with the new version and fix the errors).  

Hope this helps.  

Bryan
