XER encoding rules for Z39.50

There is a good chance no-one really cares, however I have just had a go
at converting the ASN.1 of Z39.50 into a format that is closer to what
you would really generate for XER (XML encoding instead of BER).

I don't guarantee its correct. Our next server release will include XER
support natively (and that will be correct), but I found the ASN1->XER
rules a bit error prone when done by hand, so I knocked up this cheat-sheet.
I just thought I would share it in case anyone was interested.

The page is at:

I have also been playing with putting together an XER->Z39.50 gateway
if anyone is interested (but I am guessing probably not). The nice thing
about XER though is it allows Z39.50 access from any programming language
with strings and sockets.
