Element <else>

Purpose: is the attributeless fallback branch of a .

Why: Use it as the unconditional final branch when no earlier condition matched.

Example

1
<else/>

Decision guide

Business value: Makes fallback behavior explicit and reviewable.

  • Use when

    • A condition block needs work to run after all prior branches fail.

  • Choose another approach when

    • A condition must still be evaluated or no fallback behavior is required.

  • Prerequisites

    • Place it last inside condition.

  • Alternatives

    • Use else-if when the additional branch has its own condition. (See: <else-if>)

Assemble nested objects, conditional lists, arrays, and branches

Use this shape when one deterministic product combines nested records, heterogeneous list entries, literal arrays, and mutually exclusive fields.
