> but my reaction has always been that > the number function is there for a reason You don't believe in anachy and accidental development via evolution?:-) number() forces coersion to numbers at places where it wouldn't happen automatically. Notably foo[@bar] takes foo elements that have a bar attribute foo[number(@bar)] takes the foo element whose position() is equal to the numeric value of its bar attribute. test="@foo=1" is false if the source has foo="1.0" but test="number(@foo)=1" would be true in that case.
