generating WML with a doctype using translets

[COUNSELL,MIKE (HP-UnitedKingdom,ex1)]

I am trying to generate WML using a translet but I am having trouble
producing output with the doctype that is specified in the XSLT source
document. I have noticed that in the
org.apache.xalan.xsltc.runtime.TextOutput class the setDoctype method is
empty except for a comment that says "// TODO - pass these to the SAX output
handler - how?" Can anyone shed some light on this and help me to generate
content with the doctype from the XSLT?
