    This method is called for saving of documents over all filters which are
    not SfxFilterFlags::OWN or for which no clipboard format has been registered
    (thus no storage format that is used). In other words, with this method
    it is exported.

    Files which are to be opened here should be opened through 'rMedium'
    to guarantee the right open modes. Especially if the format is retained
    (only possible with SfxFilterFlags::SIMULATE or SfxFilterFlags::OWN) file which must
    be opened STREAM_SHARE_DENYWRITE.

    [Return value]

    bool                true

                        false
                        The document could not be saved, an error code is
                        received by <SvMedium::GetError()const>
