<type>ConfigurationAccess</type> applies to implementations of this service
as well. Therefore an implementation will support one of several alternate
services describing its <em>Container</em> role and one of several alternate
services describing its <em>Element</em> role. These services are
extensions of the respective services documented for <type>ConfigurationAccess</type>.
</p>
<ul>
<li><em>Container</em> role:
A <em>group</em> permits changing child values.
A <em>set</em> permits inserting and removing contained elements.
</li>
<li><em>Element</em> role:
The root element of a modifiable tree provides extended functionality
to control processing of changes for the entire tree (fragment) by
supporting <type scope="com::sun::star::util">XChangesBatch</type>.
For elements of a <em>set</em> or a <em>group</em> no additinal
interfaces are supported.
