(#11518 An error occurred ) ``` * (M) docs/options.md - Add two addition field options that are used as markers for specific YANG types in generated protobufs. ``` This adds two additional unique `FieldOptions` field numbers for annotat YANG leaf-lists, and leaf-lists of unions that need specific handling in field option code.
