notes: |
If the extension set name is not unique, then the extension set identifier
will match the first extension set with that name in the search order.
However, this extension set identifier is not guaranteed to correspond to the
desired extension set. The extension set identifier is used with other
extension related directives to access the extension set.
The objects are searched from lowest to the highest index. Only the local
node is searched.
