I assure you that a lot of people are using XML and even creating applications that use XML without thinking in such terms (conceptual data modeling, UML, etc.). Rather than a liability, I believe that is XML's strength. Agreement on syntax while being agnostic about how you want to use the syntax is what has enabled so many different approaches to using XML. The common syntax means we can make those different applications talk to each other. I think the "cultural break between the XML ecosystem and the old-style, database-oriented data modeling techniques" is overall a good thing and far from disastrous. My two cents. :-) Evan
