Geoff Shuetrim	06-02-2008 at 09:23:00	Changed the output data type to avoid forcing type conversion to a string. This change was suggested by Herm Fischer to better handle situations where the custom attribute has a QName data type. Changed the output to an empty sequence rather than a string to avoid confusion in situations where the attribute is provided by has a value that is the empty string. Fixed up the typo referencing the xbrli:periodType attribute rather than the custom attribute.
