This shouldn't even be considered. Attributes are used for far more than
what the above paragraph describes. Typical uses include many classic search
criteria such as meta-information about authorship, revision stages, and
revision dates. The sole purpose of ID type attributes is to uniquely
identify elements, and unique identifiers ought to be pretty handy when
searching for information. A system that can quickly locate elements with a
particular value in an IDREF type attribute would be very useful in link
maintenance and implementation.

Come to think of it, a system that left out element content might be more
useful than one that left out attributes. Of course I'm kidding, but a nice
thing about implementing storage of attributes is that they map more easily
to relational databases where ID and IDREF attributes can be easily indexed
for searching.
