Arnold, thanks. In my understanding XML and STEP as system neutral data
wrappers are
 roughly similar mechanisms. I am just wondering if the concept of a
modeling level is 
feasible/practical for a *generalized* markup language.
In ebXML and BizTalk you see that modeling levels appear.

Also with richer data type support soon available in XML via XSchema, I
wonder if 
mechanisms like EXPRESS-X are actually avoidable (to guarantuee against
critical
data loss). Any thoughts on this? Len?

Very interesting.

Thanks, I'll check that out.
