Title: XML Attributes

thanks Leif. We have a DTD, and I have read the book a zillion times but have never seen reference to such syntax. And I've hunted through just about every site offering DTD tutorials. This must be a standard they introduced last week. Now hunting around looking for reference material.This stuff is so mickey-mouse. So what happenns if the field is alphanumeric? How do you code for a range of special characters? do you have to know the ASCII collating sequence? The problem with the PC world is that of shifting standards. Going through this exercise makes me feel guilty about taking 5250 for granted. 

Thanks again.

s there some mysterious way that XML allows the developer to define some more sophisticated attributes than just a string of indeterminate length? (as long as it's between two "well-formed" tags?

===> to be a valid XML document you must include a DTD. Within the DTD you can

define elements to be just as you like them: e.g.:   NUM3:= [0-9][0-9][0-9]

to indicate an element consisting of exactly 3 valid digits.
