Parameter

The Parameter element represents a method parameter used as part of a MethodSignature in MethodDef, ConditionDef, or RangeCheck.

Element Name	Parameter
Parent Elements	MethodSignature
Element XPath(s)	/ODM/Study/MetaDataVersion/ItemDef/RangeCheck/MethodSignature/Parameter /ODM/Study/MetaDataVersion/MethodDef/MethodSignature/Parameter /ODM/Study/MetaDataVersion/ConditionDef/MethodSignature/Parameter
Element Textual Value	None
Attributes	Name, DataType, Definition, OrderNumber
Child Elements	None
Usage/Business Rules	Business Rule(s): If the FormalExpression includes input arguments, a Parameter must be provided for each argument. A Parameter identifies values passed to a Method that may be processed by a FormalExpression. To maintain the relative simplicity of MethodDef implementations, default values and optional parameters are not explicitly supported.

Attribute	Schema Datatype or Enumeration	Usage	Definition	Business Rules
Name	name	Required	The parameter name - typically the name of an ItemDef referenced in the ItemGroupDef.	When the MethodDef is referenced by an ItemGroupDef, the result will provide a data row. When the MethodDef is refernced by an ItemRef, the result provides ItemData for the corresponding ItemRef.
DataType	(text \| integer \| decimal \| float \| double \| date \| time \| datetime \| string \| boolean \| double \| hexBinary \| base64Binary \| hexFloat \| base64Float \| partialDate \| partialTime \| partialDatetime \| durationDatetime \| intervalDatetime \| incompleteDatetime \| incompleteDate \| incompleteTime \| URI )	Required	Parameter datatype.	The DataType must match the ItemDef/DataType for the Parameter.
Definition	text	Optional	A free-text definition of the parameter	Non-translatable text.
OrderNumber	positiveInteger	Optional	Position of the Parameter in the MethodSignature
