* Content negotiation enum.

* the default encoding of XML infoset for an outbound message unless informed
* otherwise by a previously received inbound message.
* (The client transport initially and pessimistically assumes that a service
* does not support anything other than the default encoding of XML infoset.)
*
* A value of {@link #optimistic} means the client transport will assume
* a non-default encoding of XML infoset for an outbound message.
* (The client transport optimistically assumes that a service
* supports the non-default encoding of XML infoset.)
