One QoS policy value.

Every field a DDS-XML document can omit is Option, so an unwritten field stays distinguishable from one written at its default. A profile that inherits from another needs exactly that distinction to know which fields to take from its base. Spec §3.7.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
