toXml( String schemaLocation )?

It's easy to design wsdl from scratch. It's not so easy to define wsdl against an existing model. A standard Object api in which webservice layers can use to build messages would be nice.

Document toXml( String schemaLocation ){
//factory that uses an extensible set of xml
//producers
return DomFactory.produceXml( this, schemaLocation );
}
