nilValue List of DFDL string literals, List of logical values, Character Specifies the text strings that are the possible literal or logical values of the element. If ‘literalValue’ then nilValue specifies a white space separated list of DFDL literal strings that are the possible representation values for nil. On input the element value is nil if the data matches literal strings. On output if the element value is nil the first nilValue is output. Only applicable when representation is 'text' If ‘logicalValue’ then nilValue specifies white space separated list of logical values that are the possible logical values for nil. On input the element value is nil if the data, converted to its logical type, matches any of the logical values. On output if the element value is nil, the first nilValue is converted to its physical representation and output. If 'literalCharacter' then nilValue specifies a single character or byte that, when repeated to the length of the element, is the nil representation value. If a character, then it can be specified using a literal character or using DFDL entities. If a character is specified when lengthUnits='bytes' then the nilValue must be a single-byte character. If a byte, then it must be specified using a single %#r entity If a byte is specified when lengthUnits='characters' then the encoding must be a fixed-width encoding On input the element value is nil if all characters in the data match the nilValue character . On output if the element value is nil the nilValue character is output to the required length. Annotation: dfdl:element(simpleType) Alan: OK - now that we've moved the text from one box in the table to the next we need to be a bit more specific concerning the references. For example, in the above the 'literal value' does not refer to this property but to the value of nillKind. Also, we tend to use 'on parsing' and 'on unparsing' instead of 'on input' and on 'output'.There are also a couple of very small nits I wanted to change as well. List of DFDL string literals, List of logical values, Character Specifies the text strings that are the possible literal or logical values of the element. If dfdl:nillKind is ‘literalValue’ then nilValue specifies a white space separated list of DFDL literal strings that are the possible representation values for nil. On parsing the element value is nil if the data matches one of the literal strings in the list. On unparsing if the element value is nil the first nilValue from the list is output. Only applicable when representation is 'text'. If dfdl:nillKind is ‘logicalValue’ then nilValue specifies a white space separated list of logical values that are the possible logical values for nil.

Steve is away next week so I will cancel the WG call. Can you please send corrections to this draft by Tuesday so that I can get it into the next draft of the spec.
