question: private boolean serializeCompactRDFAttrProps ( XMPNode parentNode , int indent ) throws IOException { boolean allAreAttrs = true ; for ( Iterator it = parentNode . iterateChildren ( ) ; it . hasNext ( ) ; ) { XMPNode prop = ( XMPNode ) it . next ( ) ; if ( canBeRDFAttrProp ( prop ) ) { writeNewline ( ) ; writeIndent ( indent ) ; write ( prop . getName ( ) ) ; write ( "=\"" ) ; appendNodeValue ( prop . getValue ( ) , true ) ; write ( '"' ) ; } else { allAreAttrs = false ; } } return allAreAttrs ; }
target:  Write each of the parent's simple unqualified properties as an attribute. Returns true if all of the properties are written as attributes.
