Probably the MIME publish plugin

http://www.xmlblaster.org/xmlBlaster/doc/requirements/mime.plugin.publishfilter.html

is the right place
to decode when the messages are received and
the MIME access plugin

http://www.xmlblaster.org/xmlBlaster/doc/requirements/mime.plugin.accessfilter.html

the right place to encode when the message is
put to the subscribing clients queue
