	 A1, A2: Notice how the types **CONFLICT** here. In Qpid and Rabbit,
	         's' means a signed 16-bit integer; in 0-9-1, it means a
	          short string.
	
	 B: Notice how the signednesses **CONFLICT** here. In Qpid and Rabbit,
	    'l' means a signed 64-bit integer; in 0-9-1, it means an unsigned
	    64-bit integer.
	
	I'm going with the Qpid/Rabbit types, where there's a conflict, and
	the 0-9-1 types otherwise. 0-8 is a subset of 0-9, which is a subset
	of the other two, so this will work for both 0-8 and 0-9-1 branches of
	the code.
