I've got a technical problem concerning SignPuddle. When you obtain XML dump of the data from SignPuddle, the sbml.xml file starts with <!DOCTYPE sbml SYSTEM "http://www.signbank.org/SignPuddle1.5/sbml.dtd"> However, this DTD seems to contain only a comment, and my XML parser stops with an error. So I report a bug to the list. Best, Olaf Matyja
