ASN.1 of new Z39.50 spec

Hi again,

One of the programmers here got a printout of the revised spec off
the LoC site, and had a few questions. (We were going to have a go
at XER - partly for the fun of it - but wanted to use the 'official'
ASN.1 as it impacts the XER encoding.) I mentioned Dedup before, but
here is a longer list of issues.

Thanks for any feedback.

========================================================================
Notes on the ASN.1 in the new Z39.50

1) The Dedup and PQESCorrection Options start with a uppercase letter. 
   This is illegal in ASN.1

2) They appear to have dropped the ASN.1 of DIAG-1. Was this intended?

3) They appear to have dropped the ASN.1 of resource report format 1.
   Was this intended? 

3) The ASN.1 of resource report format 2 mentions resource report 
   format 1 but resource report format 1 does not appear to be included.

4) APDU defines duplicationDetectionRequest as

   duplicationDetectionRequest [49] IMPLICIT ExtendedServiceRequest
                                             ^^^^^^^^^^^^^^^^^^^^^^

5) eSpec-1 is missing. Was this intended?

6) In eSpec-2 the field VarientRequest of ElementRequest starts
   with an uppercase 'V'   
   TagType and TagValue fields also start with uppercase letters.
