That code gets the 'version' and 'standalone' attributes from the XML
declaration, so that they can be exposed in some DOM attributes on the
DOM 3 Document object.
It is strange that parser would become null in startElement, since that
should only be called from within the parser’s parse method, and the
only time parser is set back to null is at the end of createDocument.
When I get some time(!) I’ll investigate.
