base_ property
Base is the branch the work is proposed INTO, by short name. Defaults to the repo's default branch, which is where a proposal goes when nobody says otherwise.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
