///   valid or if the FixedDocumentSequence contained in the file is
///   incorrect.  (In this sample the files are hardcoded.)</remarks>
private void LoadDocumentViewer(string xpsFilename)
    // Save a reference to the currently open XPS package.
    XpsDocument oldXpsPackage = _xpsPackage;

    // Open the package for the new XPS document.

    FixedDocumentSequence fixedDocumentSequence =

    // Set the new FixedDocumentSequence as
    // the DocumentViewer's paginator source.
    docViewer.Document =
        fixedDocumentSequence as IDocumentPaginatorSource;

    // If there was an old XPS package, close it now that
    // DocumentViewer no longer needs to access it.
    if (oldXpsPackage != null)

    // Leave the new _xpsPackage open for DocumentViewer
    // to access additional required resources.
