The fact that //@id is indexed in the database, not (1 to 10000), which
is computed dynamically.
I remind that max() still can not use the index in eXist. That's why it
is much slower than expected compared to (some) other usages of //@id.
Well, using an obvious shortcut for max(1 to 100000) might also be
considered in the future :-)
