RE: Help deciphering someone else's XML schema

Michael,

Thanks for the help.  It gives me something to work with, and to talk to the
document originator.

I couldn't find an answer in the FAQs, so I posted my original question
here. I also have some formatting issues, but I'll get to those as soon as I
figure out why this doesn't work.

I will contact EditiX about the Schema problem.
