Is there any chance that someone could elaborate? 
I've heard that there are lots of these anecdotes, but
I don't know any details. 

Certainly a straightforward normalization of a serious
document-oriented schema such as DocBook would lead to
a nightmarish number of tables, but I'm not clear
offhand on why normalizing just the metadata would be
such a problem.
