-- @DefaultValueSpecification@ is a list of default values for a
-- constituent sub slot in a composite slot. Default values are used when
-- Amazon Lex hasn\'t determined a value for a slot. You can specify
-- default values from context variables, session attributes, and defined
-- values. This is similar to @DefaultValueSpecification@ for slots.
--
-- @PromptSpecification@ is the prompt that Amazon Lex uses to elicit the
-- sub slot value from the user. This is similar to @PromptSpecification@
-- for slots.
