...and will also use it for port 111, which is appropriate for the RPC
dissector (as port 111 is used for an RPC protocol, namely
portmap/rpcbind).
However, it's not always appropriate to specify a port number for a
protocol; I suspect it's not appropriate in Andreas' dissector, for
example.
In those cases, you do
dissector_add_handle("tcp.port", xxx_handle);
(using the appropriate dissector table and handle).
