Yes its fine, however I would just place all that code in one
component.
class ServiceCompositionEngineComponent extends Object {
function startup();
function getRespType($responseType,$text,$model,$mappings = array());
function jsonParse($response,$model,$mappings = array());
function xmlParse($response,$model,$mappings = array());
}
And it should be $xmlpsr, not var xmlpsr.
