ORA-30931: Element 'document-groups' cannot contain mixed text

Question

I get this error when I try to create a schema based XML resource as soon as the XML contains utf8 characters.
declare
xmlref XMLType;
result BOOLEAN;
BEGIN
SELECT     XMLElement ( "document-groups",
     XMLAttributes ( 'http://www.w3.org/2001/XMLSchema-instance' AS "xmlns:xsi",
'CCRDocGroupsAndTypes.xsd' AS "xsi:noNamespaceSchemaLocation" ),
     XMLAgg (
     XMLElement ("document-group",
     XMLAttributes (DECODE(aa.aa_id,5,'FAQ',7,'SOFTWARE',2,'WARRANTY') AS "id" ),
     XMLElement ("last-modified-date", '2004-06-23T17:10:20' ),
     XMLElement ( "document-types",
     XMLAgg (
     XMLElement ("document-type",
     XMLAttributes (dtt.dt_cd AS "id" ),
     XMLElement ("description", dtt_desc) ,
     XMLElement ("language",
     XMLAttributes ( lang_cd AS "id" ) ) ) ) ) ) ) )
INTO      xmlref
FROM     m_doctype_translation      dtt
,     m_document_type          dt
,     m_application_area     aa
WHERE     dt.dt_cd     = dtt.dt_cd
AND     aa.aa_id     = dt.aa_id
--AND     dtt.lang_cd      = 'ENG'
AND     aa.aa_id     IN (2,5,7)
GROUP     BY aa.aa_id
result := DBMS_XDB.createResource(
'/atg/xxx.xml'
,xmlref );
COMMIT;
END;
Any ideas?
