Hi Rui,

Thanks for your patch. It looks good. I'll apply it now.

Neither are we :-) but I've been treating content_type as if it were a 
MIME type in other situations, so we may as well do the same here.

This seems reasonable. I don't like the idea of doing any parsing of 
this header, yet, though, until the formats are more precisely defined 
in the various standards.

I think they're different - does JMSType always line up exactly with 
MIME content-type? Certainly in AMQP, there's an equivalent of the 
JMSType field which is otherwise undocumented, and is distinct from the 
content-type header. (The JMS mappings in 0-8 and 0-9 are a bit of a mess.)
