SBGN-ML export may produce invalid notes
When exporting in SBGN-ML, nodes that are skipped because not SBGN-compatible are reported in a <notes> element at the end of the <sbgn> element; this <notes> element is not properly formatted as it is not valid xhtml (the <body> element lacks xmlns="http://www.w3.org/1999/xhtml").
