return XMLElement(lib.lsl_get_desc(self.obj))<EOL>
Extended description of the stream.

        It is highly recommended that at least the channel labels are described 
        here. See code examples on the LSL wiki. Other information, such 
        as amplifier settings, measurement units if deviating from defaults, 
        setup information, subject information, etc., can be specified here, as 
        well. Meta-data recommendations follow the XDF file format project
        (github.com/sccn/xdf/wiki/Meta-Data or web search for: XDF meta-data).

        Important: if you use a stream content type for which meta-data 
        recommendations exist, please try to lay out your meta-data in 
        agreement with these recommendations for compatibility with other 
        applications.
