When reading, assume that section 15.13 has been updated to include complex as well as simple elements. No change to enums. missingValueInitiatorPolicy Enum Valid values ‘required', ‘prohibited' Specifies whether to expect an initiator when an element is missing. Ignored unless dfdl:initiator is specified and is not "" (empty string). 'required' - Indicates that the dfdl:initiator followed by empty content is the required syntax to indicate that the element is missing. 'prohibited' - Indicates that empty content is the required syntax to indicate that the element is missing. The presence of an initiator implies that real content must follow. Use of ‘prohibited’ implies an ordered sequence. If used on an initiated element of an unordered group it is a schema definition error. If the element is required, defaulting occurs as defined above. This property also applies on unparsing, when the data to be written (after nil value and default value processing) is empty content. Annotation: dfdl:element Unparsing. The branch of a choice output when a complex element is required but missing from the infoset is the first branch of the choice that does not result in a processing error.
