]FIGCAPTION]

> This appendix describes data objects used by conforming PKI
>    components in an "ASN.1-like" syntax.  This syntax is a hybrid of the
>    1988 and 1993 ASN.1 syntaxes.  The 1988 ASN.1 syntax is augmented
>    with 1993 UNIVERSAL Types UniversalString, BMPString, and UTF8String.
>    The ASN.1 syntax does not permit the inclusion of type statements in
>    the ASN.1 module, and the 1993 ASN.1 standard does not permit use of
>    the new UNIVERSAL types in modules using the 1988 syntax.  As a
>    result, this module does not conform to either version of the ASN.1
>    standard.
>    This appendix may be converted into 1988 ASN.1 by replacing the
>    definitions for the UNIVERSAL Types with the 1988 catch-all "ANY".
