<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
XContentCreator::createNewContent() 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
com::sun::star::io::XInputStream 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
InsertCommandArgument::ReplaceExisting"
to false and there is already a stream with the title given by the
content's URL.
