I'm sorry, when I wrote "properties defined by RFC 2518" I meant "one of 
the eight DAV properties" (which are listed in section 13 of RFC 2518).

Note that a server could support DASL for search without supporting WebDAV, 
including PROPFIND and PROPATCH, that is, with no support whatsoever for 
anyone reading or setting any WedDAV properties.  The properties might be 
added by the arbiter in the course of its indexing or operations (e.g.

But this is likewise true of many properties, no?
