• the ability for the dfdlx:repValues property to be omitted and its value implied
  • generation schemas should always add the dfdlx:repValues property for now.
• the ability to synthesize ILLEGAL_N from an unmapped integer.
  • Currently a processing error occurs
  • Schemas should define explicit ILLEGAL_N enumeration values for all integers, along with a pattern facet with a regular expression indicating that the string cannot begin with "ILLEGAL_" such as "[^(ILLEGAL)].*"
    • This works because within a simple-type definition enumerations and patterns are ANDed. One of the enumerations must be satisfied, AND one of the patterns (if there is more than one pattern).
    • This could be extended, if other enumeration values want to be considered well-formed, but invalid the regular expression can also exclude those E.g., UNDEFINED, UNUSED, or other marker enumeration values.
