With everything normalized (aka "shredded") down to the level of 1 
element/attribute per column?  Back when I was dodging SGML dinosaurs 
and doing this kind of thing, the granularity was much higher.  If 
we're talking about the relational model, as opposed to pragmatic use 
of an RDBMS, I think we have to talk about normalized data.  But I 
don't want to get into this particular religious debate, shudder.  My 
point isn't that  you can't use an RDBMS as a nice metadata and CLOB 
repository for SGML/XML and write code to dynamically generate IETMs, 
but for what it's worth  I had a real epiphany when I discovered how 
much easier it was to do this with XML DBs.
