Tomas,

I want to extend asn2wrs to generate ASN.1 type information for a given hf
that I can use to bring up ASN.1 spec at the appropriate location. Whilst I
have done this with a separate "#include packet-XXX-typearr.c", I was
wondering if the asn2wrs generated "blurb" could be used?

I can't quite tell what the asn2wrs wants to set the "blurb" to -  but it is
often blank in asn2wrs generated files.

Attached is a patch (for discussion only) for what I am looking, so you can
see what I mean. 

With this patch, packet-x509.c goes from:
...
    { &hf_x509af_version,
      { "version", "x509af.version",
        FT_INT32, BASE_DEC, VALS(x509af_Version_vals), 0,
        "", HFILL }},
    { &hf_x509af_serialNumber,
      { "serialNumber", "x509af.serialNumber",
        FT_INT32, BASE_DEC, NULL, 0,
        "", HFILL }},
    { &hf_x509af_signature,
      { "signature", "x509af.signature",
        FT_NONE, BASE_NONE, NULL, 0,
        "", HFILL }},
    { &hf_x509af_issuer,
      { "issuer", "x509af.issuer",
        FT_UINT32, BASE_DEC, VALS(x509if_Name_vals), 0,
        "", HFILL }},
    { &hf_x509af_validity,
      { "validity", "x509af.validity",
        FT_NONE, BASE_NONE, NULL, 0,
        "Certificate/signedCertificate/validity", HFILL }},
    { &hf_x509af_subject,
      { "subject", "x509af.subject",
        FT_UINT32, BASE_DEC, VALS(x509af_SubjectName_vals), 0,
        "Certificate/signedCertificate/subject", HFILL }},
    { &hf_x509af_subjectPublicKeyInfo,
      { "subjectPublicKeyInfo", "x509af.subjectPublicKeyInfo",
        FT_NONE, BASE_NONE, NULL, 0,
        "Certificate/signedCertificate/subjectPublicKeyInfo", HFILL }},
to:

    { &hf_x509af_version,
      { "version", "x509af.version",
        FT_INT32, BASE_DEC, VALS(x509af_Version_vals), 0,
        "x509af.Version", HFILL }},
    { &hf_x509af_serialNumber,
      { "serialNumber", "x509af.serialNumber",
        FT_INT32, BASE_DEC, NULL, 0,
        "x509af.CertificateSerialNumber", HFILL }},
    { &hf_x509af_signature,
      { "signature", "x509af.signature",
        FT_NONE, BASE_NONE, NULL, 0,
        "x509af.AlgorithmIdentifier", HFILL }},
    { &hf_x509af_issuer,
      { "issuer", "x509af.issuer",
        FT_UINT32, BASE_DEC, VALS(x509if_Name_vals), 0,
        "x509if.Name", HFILL }},
    { &hf_x509af_validity,
      { "validity", "x509af.validity",
        FT_NONE, BASE_NONE, NULL, 0,
        "x509af.Validity", HFILL }},
    { &hf_x509af_subject,
      { "subject", "x509af.subject",
        FT_UINT32, BASE_DEC, VALS(x509af_SubjectName_vals), 0,
        "x509af.SubjectName", HFILL }},
    { &hf_x509af_subjectPublicKeyInfo,
      { "subjectPublicKeyInfo", "x509af.subjectPublicKeyInfo",
        FT_NONE, BASE_NONE, NULL, 0,
        "x509af.SubjectPublicKeyInfo", HFILL }},

Comments?
