Note that is content-encoding, not content-type. Having content-type 
exposed in JMS is indeed very valuable. content-encoding as a separate 
field in 0-10 is not used as far as I'm aware. The content-type is 
(however in the messaging API it is exposed directly, these special 
properties are only used to access 0-10 specific fields not deemed to 
have generic counterparts).
