I will attempt to answer some of these questions for Karen that
Alan forwarded:
>

Yes - definately. XML requires the same rigorous analysis that X12
and UN/EDIFACT required. If the analysis isn't done, then you can
be assured that the XML isn't any good.
When looking at XML for existing X12 or UN/EDIFACT messages, it is
wise to look closely at what X12 and UN/EDIFACT has accomplished. The
hard part is done - the ANALYSIS.
When developing XML, you will have to look more closely at the
relationship of data. You also have the ability to enhance the
content of the data (for exchange for internal use) that is
difficult in EDI.

Yes. There are several places where people are sending their DTDs.
http://www.biztalk.org
http://www.oasis.org
However, industry standards organizations are the real authority for
'standard' DTDs/schemas (schemas aren't a standard yet).
A very good source of information is Robin Covers bibliographic site:
http://www.oasis-open.org/cover/

No, you can't. It depends upon where you get your DTDs/Schemas. If
you get them from the standards body (which there are very few approved
ones at the moment), I think you are relatively safe that they conform
to the X12/EDIFACT mandatory/optional rules. However, if you get them
from another source, then you should do a good independent analysis
of the DTD.

I'm not aware of any. I have just updated the OFX standard for Intuit to
incorporate some tax components. I am sure that someone, somewhere is
thinking along these lines. Quickbooks and Quicken products currently
talks to banks in SGML (XML's parent).
If you aren't aware, the IRS (U.S. Internal Revenue Service for our
foreign subscribers) has been a long-time user and comsumer of SGML (XML's
parent). You can currently download all IRS forms in PDF and SGML.
I foresee a bright future of XML and tax preparation. However, I
think it would have to be done with IRS or other official country
'tax authority' participation.

Actually your questions are quite good! There is a lot of misinformation
about XML in the media and other sources. It is difficult for individuals
and organizations to begin the navigation through the XML maze.
