Depends on the DTD you use, actually.  I think attributes are more
expensive to parse; they certainly need normalization and defaulting,
which elements don't use.  Parsers fill out an auxiliary data structure
and then scan it ...

Don't get me wrong, this shouldn't be a design consideration, but I
do believe that there's a minor price to pay in _all_ parsers.
