		<p>

		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>
