- mechanism features also requires the URI Map feature, but this is
- implicit - the UI does not have to list the URI map feature as a required
- or optional feature in it's RDF data.

- <pre>
- uiext:portNotification
- uiext:noPortNotification

- and similarly with <code>uiext:noPortNotification</code> if you wanted
- to prevent notifications for a port for which it would be on by default
- otherwise. The UI is not allowed to request notifications for ports of
- types for which no transfer mechanism is specified, if it does it should
- be considered broken and the host should not load it.
