basic question: is there a mechanism for annotating/adding descriptions to basic schema types in a manner similar to annotating map keys? Example use case: annotating tuple elements. I'd like to attach more information than just :string alone. E.g. instead of:

[:tuple :uuid :string :string]

[:tuple {:type :uuid :description "The unique identifier for thing."} {:type :string :description "The thing's annotation."} {:type :string :description "The thing's title."}]
