Section 6.3 lists 'List of DFDL string literals' as one of the property types, but it is never specified as the type of 
a property. 
There are several places where the property type is not correct.
- Initiator, terminator, separator: should all be 'List of DFDL string literal', and the text should state that the 
expression returns a *list* of DFDL string literals.
- representation: should be 'Enumeration', not 'DFDL String Literal'
- extraEscapedCharacters: should be 'List of DFDL String Literal'.
- textNumberPattern:
  textNumberDecimalSeparator:
  textNumberGroupSeparator:
  textNumberExponentCharacter:
  textNumberInfinityRep:
  textNumberNanRep:
  calendarPattern:
  calendarLanguage:
  All should be 'string' ( these strings are describing ICU parameters, and DFDL mnemonics would not be meaningful to 
ICU ).
- binaryPackedSignCodes: should be 'list of character'
- binaryCalendarEpoch should be 'string' or 'ISO8601'
- occursStopValue should be 'XML string literal'
