How to get ALL validate-errors while insert xml-file into xml_schema_table

Question

How to get all validate-errors while using insert into xml_schema when having a xml-instance with more then one error inside ?
Hi,
I can validate a xml-file by using isSchemaValid() - function to get the validate-status 0 or 1 .
To get a error-output about the reason I do validate
the xml-file against xdb-schema, by insert it into schema_table.
When more than one validate-errors inside the xml-file,
the exception shows me the first error only.
How to get all errors at one time ?
regards
Norbert
... for example like this matter:
declare
     xmldoc CLOB;
     vStatus varchar
begin     
-- ... create xmldoc by using DBMS_XMLGEN ...
-- validate by using insert ( I do not need insert ;-) )      
     begin
     -- there is the xml_schema in xdb with defaultTable XML_SCHEMA_DEFAULT_TABLE     
     insert into XML_SCHEMA_DEFAULT_TABLE values (xmltype(xmldoc) ) ;
     vStatus := 'XML-Instance is valid ' ;
     exception
     when others then
     -- it's only the first error while parsing the xml-file :     
          vStatus := 'Instance is NOT valid: '||sqlerrm ;
          dbms_output.put_line( vStatus );      
     end ;
end ;

If I am not mistaken, the you probably could google this one while using "Steven Feuerstein Validation" or such. I know I have seen a very decent validation / error handling from Steven about this.
