Handling of missing attributes or empty values

This list shows what happens when missing or empty attributes are discovered:

• If an element or attribute that is defined by Path expression has an empty value or null value in the Patch document.

  The (empty) value is propagated to the Output document.

• If an element or attribute that is defined by the Path expression is missing in the Input document.

  Missing elements or attributes are created in the output document and value is taken from Patch document.

• If an element or attribute that is defined by the Path expression is missing in the Patch document.

  No action is done for this mapping and the information is logged.
