+ * There are a few key differences between validate_uuid and parse_uuid:
+ *
+ * - The struct uuid * parameter to validate_uuid is optional, so the caller
+ * can simply validate UUID format without doing anything with the result.
+ * - validate_uuid will not pass an empty string as a valid UUID, as it doesn't
+ * strictly meet the formatting requirements. parse_uuid will accept an
+ * empty string and zero out the uuid struct accordingly.
+ * - parse_uuid does additional semantic checks on clock_seq_hi_and_reserved
+ * that validate_uuid will not do.
+ *
+ * validate_uuid is intended to strictly check that it's a well-formed uuid.
