Given that the vcard is a self describing XML formatted document with each version basically expanding on previous ones. Does just editing the resulting file and changing the stated vcard version allow it to work with ancient software that is checking the vcard version number??

Thanks Matt. Editing the file with either `sed` or `awk` or using python regex is always a possibility. I just did not want to reinvent the wheel in case something already existed. From what I saw out there, there is nothing readily available, so I will roll my own editing tool from the shell probably. The only menial issue is that VCF 4.0 introduces new sub categories for many parameter "keys", so I will need to look that up for about 3650 VCards. That's about 38000 lines of text altogether, (nothing `sed` or `awk` can't handle). What I am most concerned about is parsing non-ASCII characters (UTF-16) adequately.
