Michele Issue #1 <dfdl:simpleType dfdl:lengthKind="explicit" dfdl:lengthUnits="bytes" dfdl:length="4"/> This is not correct syntax. The "dfdl:" namespace prefix for a property is only used for "short form" attributes. Change to: <dfdl:simpleType lengthKind="explicit" lengthUnits="bytes" length="4"/> Issue #3 <dfdl:discriminator test="{true}"/> I think this should be: <dfdl:discriminator test="{fn:true()}"/> 23.5.2.1 Boolean functions The following additional constructor functions are defined on the boolean type. Function Meaning fn:true() Constructs the xs:boolean value 'true'. fn:false() Constructs the xs:boolean value 'false'.
