Setting the value of an output element with a explicit data type

In the Graphical Data Mapping editor, you can use any of the xs:type transforms to cast the value of a simple type input element and set the value of a simple type output element.

For example, you want to assign a value with a specific data type to a target element that is defined as xs:anySimpleType. You can use the xs:type transform.

You can have zero or more input elements to an xs:type transform. However, you can only cast one value for an output element by using an xs:type transform. If the mapping for the xs:type transform has more than one input, any input that is not referenced by the argument of the xs:type transform will be ignored.

You can use the input elements to build a conditional expression that determines if the xs:type transform is applied or not.

You must choose the xs:type transform according to the output element data type. For example, if you have an output element with a boolean data type, you must choose xs:boolean transform.

You can use any of the following xs:any transforms:

xs:NOTATION: This function takes a primitive and casts it as notation.
xs:Qname: This function takes a primitive and casts it as int.
xs:anyURI: This function takes a primitive and casts it as anyURI.
xs:base64Binary: This function takes a primitive and casts it as base64Binary.
xs:boolean: This function takes a primitive and casts it as boolean.
You can use any of the following values: true or false.
xs:dateTime: This function takes a primitive and casts it as dateTime.
xs:date: This function takes a primitive and casts it as date.
xs:dayTimeDuration: This function takes a primitive and casts it as dayTimeduration.
xs:decimal: This function takes a primitive and casts it as decimal.
xs:double: This function takes a primitive and casts it as double.
xs:float: This function takes a primitive and casts it as float.
xs:gDay: This function takes a primitive and casts it as gDay.
xs:gMonthDay: This function takes a primitive and casts it as gMonthDay.
xs:gMonth: This function takes a primitive and casts it as gMonth.
xs:gYearMonth: This function takes a primitive and casts it as gYearMonth.
xs:gYear: This function takes a primitive and casts it as gYear.
xs:hexBinary: This function takes a primitive and casts it as hexBinary.
xs:integer: This function takes a primitive and casts it as integer.
xs:int: This function takes a primitive and casts it as signed 32-bit integer.
xs:string: This function takes a primitive and casts it as string.
xs:time: This function takes a primitive and casts it as time.
xs:yearMonthDuration: This function takes a primitive and casts it as yearMonthDuration.

Complete the following steps to set the value of a output element by using an xs:type transform:

Add an xs:type transform, for example, an xs:boolean transform, to set the value of the output element, by using either of the following methods:
1. Create an Assign transform by using either of the following methods:
  - Click the output element and drag the connector towards the input elements, releasing the connector onto a blank part of the canvas. When you release the connector, an Assign transform is created.
  - Right-click the output element and then select Create Assign.
2. Use the drop-down, and select Cast Function > xs:boolean.
Enter true into the Value field in the Properties panel for the xs:boolean transform.
You can set the value to true or false.
Optional: Define a conditional expression to control when the transform should be applied .
You define a conditional expression by using an XPath expression.

For example, to evaluate the transform, the current date has to be a date after the date specified in the element CurrentDate.
