I did say "tend to see", rather than "only see". Your example seems to 
go along with this, since it's just text organized into a database-like 
layout. I agree that this can be very useful to use in combination with 
XML processing tools, but it's still what I would consider a 
data-centric structure. Just because the original text was a play 
doesn't mean the marked-up form is document-centric.

I didn't mean to imply that these two styles of XML neatly partitioned 
the space of XML users, and I apologize if my flip usage of "Schema 
crowd" gave that impression. Many people do both data-centric and 
document-centric work using XML (including me, though most of my 
applications are data-centric). There still seems to be a substantial 
difference in style, though.
