David- If you don't know what the contents of the map will be you can specify a superclass (Object often works) or an interface, and Castor will (in order) either find a mapping for that class (the mapping doesn't have to be connected to the HashMap mapping in any way), or introspect the class (look for JavaBean-style get/set methods to determine the fields to be persisted).
That all being said, there currently is a bug report about Castor's handling of Collections and arrays as HashMap values (they marshal fine but have difficulty unmarshalling). So some of the discussion above depends on your application. Let us know if you have further questions.
