Want to include ?xml tag and schema when creating XML

Question

My database table that need to be generated in to XML are large and therefore I must use OracleXMLQuery.getXMLSAX . The output is missing the <?xml version="1.0" ?> tag. How do I get it? I am on 9i but have imported the .jar containing oracle/xml/parser/v2/XMLSAXSerializer from 10g XDK.
Also, I want the schema to be written next, before the actual XML table values.
I know that a command line parameter exists, which works for small XML files:
java oraclexml getxml -user "scott/tiger" -withDTD "select ....
How do I get the equivalent of '"-withDTD" when using
     OracleXMLQuery qry = new OracleXMLQuery(conn, "select * from "+table_name );
     qry.getXMLSAX(myStream);
     myStream.flush();
Thank you,

No. Actually, I can get the <?xml tag and DTD if my select statement contains 'where rownum=0', as the resultset is small which lets me use getXMLMetaData() .
I write it to one output file, then do another OracleXMLQuery, repeating the select statement without the where clause, and run that through getXMLSAX to get the detail.
Next, I need to scrub the data of special characters acceptable in the database but which cause problems to a browser or XML validator. (e.g. accented characters).
Finally, I will concatente the two files.
Is there a simpler way to do this?
Thanks,
