That's what I've been doing. To help with matching up the paths in OSM with those in the Definitive Statements, I've been adding prow_ref=* tags to the ways, and then ticking them off on a list I've made. The prow_ref values I've entered have been of the form "<Parish> [FP|BR|RB|BY] <num>" (e.g. "Bredon FP 2") unless there is an alternative format that is consistently used by the Council. I've found the usefulness of the Definitive Statements is quite variable. Modern descriptions are generally very good, with lots of detail and grid references included. Older ones might contain very little useful detail, and often reference historic names for places / roads that are no longer in use. In working out where paths are, I've found it very helpful to consult the Out-of-Copyright OS maps (eg via the background layers in Potlatch). These don't specifically mark PRoWs, but they do include a lot of historic paths and tracks -- many of which are now PRoW -- and various old place and road names. To help with mapping PRoW, I've collected together a few resources that others might be interested in at http://robert.mathmos.net/osm/prow/ -- including some advice for requesting Definitive Statements from Councils, various visualisation tools, and copies of the Definitive Statements I've managed to get hold of.
