Take a look at Analyzer and its NetPDL language

http://analyzer.polito.it/30alpha/

While an XML description for a dissector won't be able to handle all
types of protocols, it is enough for some protocols. It may be
worthwhile to see if NetPDL could be used in Ethereal.  I'm already
working with Fulvio (of the Analyzer team) to ensure that the PDML
output format is compatible between Ethereal and Analyzer.
