	//-------------------------------------------------------------------------
	/** provides two types of contents: Stream and Folder.

		<p>

		<b>PCP Contents</b>
		<ol>
		<li>
		A PCP Stream (<type>PackageStreamContent</type>) is a content which
		represents a file inside a package.	It is always contained in a PCP
		Folder. A PCP Stream has no children.
		</li>
		<li>
		A PCP Folder (<type>PackageFolderContent</type>) is a container for
		other PCP Folders and PCP Streams.
		</li>
		</ol>

		<p><b>URL Scheme for PCP Contents</b>

		<p>Each HCP content has an identifier corresponding to the following
		scheme:

		<ul>
		<li>
		package-URL    = "vnd.sun.star.pkg://" orig-URL [ abs-path ]
		</li>
		<li>
		abs-path       = "/" path-segments
		</li>
		<li>
		path-segements = segment *( "/" segment )
		</li>
		<li>
		segment        = pchar
		</li>
		<li>
		pchar          = unreserved | escaped | ":" | "@" | "&" | "="
		                 | "+" | "$" | ","
		</li>
		<li>
		unreserved     = alphanum | mark
		</li>
		<li>
		mark           = "-" | "_" | "." | "!" | "~" | "*" | "'" | "(" | ")"
		</li>
		<li>
		escaped        = "%" hex hex
		</li>
		<li>
		orig-URL       = 1 *( unreserved | escaped | "$" | "," | ";"
        		         | ":" | "@" | "&" | "&" | "=" | "+"
		</li>
		</ul>

		<p>Examples:

		<ul>
		<li>
		vnd.sun.star.pkg://file:%2F%2F%2Fe:%2Fmy.xsw/
		( The root folder of the package located at file:///e:/my.xsw )
		</li>
		<li>
		vnd.sun.star.pkg://file:%2F%2F%2Fe:%2Fmy.xsw/Content
		( The folder/stream named "Content" that is contained in the root
		folder of the located at file:///e:/my.xsw )
		</li>
		<li>
		vnd.sun.star.pkg://file:%2F%2F%2Fe:%2Fmy.xsw/Content%20A
		( The folder/stream named "Content A" that is contained in the root
		folder of the located at file:///e:/my.xsw )
