-- Remove versions from the specified schema. A version number or range may
-- be supplied. If the compatibility mode forbids deleting of a version
-- that is necessary, such as BACKWARDS_FULL, an error is returned. Calling
-- the @GetSchemaVersions@ API after this call will list the status of the
-- deleted versions.
--
-- When the range of version numbers contain check pointed version, the API
-- will return a 409 conflict and will not proceed with the deletion. You
-- have to remove the checkpoint first using the @DeleteSchemaCheckpoint@
-- API before using this API.
--
-- You cannot use the @DeleteSchemaVersions@ API to delete the first schema
-- version in the schema set. The first schema version can only be deleted
-- by the @DeleteSchema@ API. This operation will also delete the attached
-- @SchemaVersionMetadata@ under the schema versions. Hard deletes will be
-- enforced on the database.
--
-- If the compatibility mode forbids deleting of a version that is
-- necessary, such as BACKWARDS_FULL, an error is returned.
