Are you sure that's necessary? Whenever I write a semantic template, I
use {{#if: statements to make sure that no annotation takes place unless
the relevant parameter exists. And a null number strikes me as a
show-stopper if we ever wanted to do arithmetic with those annotated
numbers. Which is something I've always wanted to do.
