• dfdlx:inputTypeCalc
  • Applies to xs:simpleType
  • Requires dfdlx:repType to also be present
  • Is a DFDL expression
  • On parse, first parse according to the repType, then populate the value of this element to the result of evaluating the dfdlx:inputTypeCalc expression
  • The value of the repType may be accessed by the expression through the dfdlx:repTypeValue() functionrepTypeValue functions
• dfdlx:ouputTypeCalc
  • Applies to xs:simpleType
  • Requires dfdlx:repType to also be present
  • Is a DFDL expression
  • On unparse, first evaluate this expression, then unparse according to the repType as if the logical value were the result of evaluating this expression
  • The original logical value of this type may be accessed by the expression through the dfdlx:logicalTypeValue() functionlogicalTypeValue functions
• dfdlx:repValues
  • Applies to xs:enumeration and xs:simpleType
  • A space separated list of values
  • Values must be of a type consistend with repType
  • When applied to xs:enumeration:
    • Defines a KeySet-Value transform, and associates the annotated enumeration value with the listed keys
    • Adds the listed values to the repValue set of the parent simpleType
  • When Applied to xs:simpleType
    • Adds the listed keys to the repValue set of the parent
    • This set will be used by xs:choice when choiceBranchKeyKind=byType
• dfdlx:repValueRanges
  • Applies to xs:enumeration and xs:simpleType
  • Requires dfdlx:repType to be present and refer to an integer type
  • A space separated list of integers defining ranges of integers
  • Takes the form “min1 max1 min2 max2 … minN maxN”
  • Represents the set of integers described by the union of the intervals [mink, maxK]
  • Behaves as if all members of this set were included in the dfdlx:repValues annotation

• dfdlx:inputTypeCalcInt(f: QName, x:Any)
  • f must be a constant QName resolving to a simpleType with a transform defined
  • The repType of said transform must match the type of x
  • The type f must be a restriction of xs:int
  • Returns the result of applying the inputTypeCalc function assotiated with f to x
• dfdlx:inputTypeCalcString(f: QName, x:Any)
  • Behaves like dfdlx:inputTypeCalcInt(f: QName, x:Any) except that f must be a string type, and a string will be returned
• dfdlx:outputTypeCalcInt(f: QName, x:Any)
  • f must be a constant QName resolving to a simpleType with a transform defined
  • The repType of said transform must be a restriction of xs:int
  • The type f must match the type of x
  • Returns the result of applying the outputTypeCalc function assotiated with f to x
• dfdlx:outputTypeCalcString(f: QName, x:Any)
  • Behaves like dfdlx:inputTypeCalcInt(f: QName, x:Any) except that the repType associated with f must be a restriction of xs:string, and a string will be returned
• dfdlx:outputTypeCalcNextSiblingInt(f: QName, x:Any)
  • The following sibling must be a simpleType whose repType is a restriction of xs:int
  • Returns the result of applying the outputTypeCalc function associated with the type of the following element to the value of the following element
• dfdlx:outputTypeCalcNextSiblingString()
  • Behaves like dfdlx:outputTypeCalcNextSiblingInt, except the repType must be a restriction of xs:string, and a string will be returned
• dfdlx:repTypeValuerepTypeValueInt()
  • Can only be called from inside dfdlx:inputTransform
  • Returns the value of the underlying repType, wehn the underlying repType has an int value
• dfdlx:repTypeValueString()
  • Can only be called from inside dfdlx:inputTransform
  • Returns the value of the underlying repType, wehn the underlying repType has an string value
• dfdlx:logicalTypeValueInt()
  • Can only be called from inside dfdlx:outputTransform
  • Returns the logical value of this element when the logical type is an int type.
• dfdlx:logicalTypeValueString()dfdlx:logicalTypeValue
  • Can only be called from inside dfdlx:outputTransform
  • Returns the logical value of this element when the logical type is a String type.
