It's there for out-of-band transports. Say that you use CORBA to create two 
mqueue streams between A and B. A creates the first stream, queries for the 
size of the data, and then, over corba, creates a stream at B, with the same 
data size. As such, both endpoints are created with the correct setting.

I need more time to think about this. We could create a datasource that reads 
the data object...
