Retrieving properties
At present, spec. defines a method called SEARCH which performs a limited search of the properties defined on a resource, and can search on the name and the value.
Pro: allows retrieval of only specific properties
Con: there is no way to specify a set of resources on which to perform the search -- cannot easy search a whole server (however, specifying a full-power search is really hard, and is out of scope)
- search is an expensive operation
