Eddie Epstein commented on UIMA-1129:
-------------------------------------

There appears to be a bug on delta CAS serialization for content added to a 
named view. For my scenario under test, the input CAS to a service has a 
single, named view. The service adds FS to that view, but the delta CAS output 
assigns all the new content to _InitialView. 

Probably related, according to a Cas dump done from inside the service, the 
_InitialView is created during service processing, although it has no content.



> XMI serialization support for delta CAS

> Extend XMI serialization to enable serializing only the changes to the CAS.  
> The requirement for delta CAS support in order to to reduce serialization 
> overhead associated with remote services is described in the wiki page found
