Default PID vs. PDL

Hey all,

while writing the Wireshark dissector I ran into a RDM packet that I don't know how to handle. It has a PID of 0x0401 (LAMP_HOURS) and a PDL of 2. But the spec (just bought the new one to verify) says that LAMP_HOURS should be a 32bit value. So, or the PID is wrong, or the PDL is wrong.

How should one deal with situations where PID and PDL disagree ?
