> The recent problem ( UIMA-4990 ) was caused by an improper use of a mostly 
> undocumented parameter in the XMI serialization API - the 
> XmiSerializationSharedData parameter.  This is used for handling 
> out-of-type-system data when sending a CAS to a remote service, and for 
> merging multiple CASes being returned from multiple remote services.  
> It is easy to misuse, and can result in strange errors (e.g. UIMA-4990 ).  
> This improvement would move this to be an internal capability, no longer 
> exposed in the API (existing API uses with it would be deprecated; instances 
> of this, if passed in, would be ignored in favor of internal memory for this).
> This would enable automatic management of this data. There is a similar 
> concept in the experimental Uima V3 prototype and an extra CAS Api for 
> eliminating the extra storage if sophisticated users know early on it won't 
> be needed.
