	to store the name-value pairs. Instead, use another ISet class
	such as OE.Core.Collections.Set.

	- Changes to the map are reflected here, and vice-versa.
	- Supports removal and removes the corresponding map entry from the map
	(Iterator.remove, Collection.remove, removeAll, retainAll and clear) .
	- Do not support add and addAll.
