Xmlns attribute in 8.1.7

Question

I am trying to process an XML file with the Oracle 8.1.7 PL/SQL XDK. I'm using Steve's helper programs from the XML book. The problem is that the document in question uses XML Schema. My script chokes whenever I attempt anything with this file. After a lot of investigation I have established that it's the xmlns attibute that it doesn't like (see testcase below).
Given that I can't upgrade to 9i just yet is there anything I can do to get this code working?
Cheers In Advance, APC
This doesn't can't find my attribute...
SQL> DECLARE
2 xdoc xmldom.DOMDocument;
3 l_file varchar2(32000) := '<MYROOT xmlnsBOB="http://www.somewhere.co.uk"> '
4 || ' <MYTAG>stuff</MYTAG> '
5 || '</MYROOT>';
6 lv_file_ref varchar2(240);
7 parser xmlparser.Parser;
8 BEGIN
9 parser := xmlparser.newParser;
10 xmlparser.setValidationMode(parser, FALSE);
11 xmlparser.parseBuffer(parser,l_file);
12 xdoc := xmlparser.getDocument(parser);
13 xmlparser.freeParser(parser);
14 lv_file_ref := xpath.valueOf(xdoc, '/MYROOT/MYTAG');
15 dbms_output.put_line('!'||lv_file_ref||'!');
16* END;
PL/SQL procedure successfully completed.
but runs okay if I rename the xmlns attribute...
