org.apache.muse.ws.resource.properties.ResourcePropertyCollection
ResourcePropertyCollection is the WSRP-based state model that is used by all WS-resources. It does not imply or require the use of any WSRP capabilities for remote clients; users must specify said capabilities in muse.xml (with the capability tag) if they want to do this.

The ResourcePropertyCollection provides a single, generic interface for reading and writing resource properties that are spread across disparate Capability objects. Read and write requests will be delegated to the appropriate {@linkplain org.apache.muse.ws.resource.WsResourceCapability capabilities} after all schema and metadata validation is done. This interface also implies the use of various listeners, which allow users to hook into the read and write requests at various points to respond to them with their own code. The crux of the ResourcePropertyCollection's role, then, is the administrative and plumbing tasks necessary to read, write, validate, and report on resource properties, but not the actual storage of the properties themselves. @author Dan Jemiolo (danj)
