vcard ORG usage

[Gavin Eadie <Gavin@xxxxxxxxx>]

In the vcard definition the ORG property is structured text.  I understand
this to mean that the minimal form of the property would appear as:

   ORG:Organization Name;

      where the trailing semi-colon is required.  Several vcards that I've
seen do not have this final character in the ORG field and so I wonder if
(a) I understand this correctly and, if so, (b) what should I do with non
conformant vcards?

I should say that I'm writing a vcard parser that doesn't requires neither
lexical tools nor ANSI library routines and it coughs over some of the
vcards out there in the world at large!
