[mb-devel] What are the valid fields to use in query parameter of xmlwebservice

[Paul Taylor]

Could someone tell me where to find the list of fields that can be used 
with the query parameter for the tracks collection, I know
track, artist and release which are equivalent to the filter parameters 
title,artist and release. But what about the rest, and are their 
additional fields not accessible from the standard filter params.
I tried adding duration and tracknum to my query but neither had any 
effect so I think I must have invalid field names.

thanks Paul
