Determines if the item may be removed from the list.
IsDeletable determines if the item is allowed to be removed from the items list. If the item is allowed to be removed the function will return True, False otherwise.<br>
IsDeletable is used in those cases where the provider generates a number of fixed items that should never be deleted. In most cases IsDeletable will be context-dependent, i.e. the item can't be deleted from the context-less item tree, but is deletable from a context-specific tree.<br>
