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[(_at_)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.
