Enforced Uniqueness of a Key

Enforced Uniqueness of a Key

The Script enforces the uniqueness of a
. This has the following consequences:
  • If two or more sibling occurrences of an input element have the same key values, the Script considers each occurrence to overwrite the previous occurrences. It uses only the last occurrence that it encounters.
  • If an occurrence of an input element is missing a key value, the occurrence is ignored.
  • If the Script outputs a keyed element, and a sibling element having the same key value already exists, the existing occurrence is overwritten.
In these cases, the Script writes a warning in the event log.
