        A PCP Folder can create other PCP Folders and PCP Streams. To create
        a new child of a PCP Folder:

        <ol>
        <li>
        Let the parent folder create a new content by calling
        <member>XContentCreator::createNewContent</member> on it. The content
        type to use for new folders is "application/vnd.sun.star.pkg-folder".
        To create a new PCP Stream, use the type
        "application/vnd.sun.star.pkg-stream".
        </li>
        <li>
        Set a title at the new folder / stream. ( Let the new child execute
        the command "setPropertyValues", which sets at least the property
        "Title" to a non-empty value ).
        </li>
        <li>
        Let the new child ( not the parent! ) execute the command "insert".
        This will commit the creation process. For streams, you need to supply
        the implementation of an
        <type scope="com::sun::star::io">XInputStream</type> with the command's
        parameters, that provides access to the stream data.
        </li>
        </ol>

        </p>

        <p>
        Another, more convenient way for creating streams is simply to assemble
        the URL for the new content ( last part of the path will become the
        title of the new stream ) and to obtain a Content object for that URL
        from the UCB. Then let the content execute the command "insert". The
        command will fail, if you set the command's parameter
        <member>InsertCommandArgument::ReplaceExisting"</member>
        to false and there is already a stream with the title given by the
        content's URL.

        </p>
