Chapter 1 : When the scoping rules were simplified in V 0.37 of spec, we removed dfd:format annotation from complex types but most of our examples in chapter 1 haven't been updated to to reflect this.. The examples should be updated to show this annotation at schema level.. <xs:complexType name="example1"> <xs:annotation> <xs:appinfo> <dfdl:format representation="binary" byteOrder="bigEndian" lengthKind="implicit" binaryFloatRepresentation="ieee" /> </xs:appinfo> </xs:annotation> <xs:sequence> <xs:element name="w" type="int"/> <xs:element name="x" type="int "/> <xs:element name="y" type="double"/> <xs:element name="z" type="float" /> </xs:sequence> </xs:complexType> Section 7.1 ( Page 47) -- Table should be updated to remove dfdl:format annotation from complex type..
