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 :-)
