Ah, (zooming in a bit in case someone else is following this), you
mean: "A custom format is any method of the object argument
(maybe acquired) that can be called without arguments. The method
result is converted into a string, if necessary." in this section:

If it weren't for your <XXX tal:content="dateobj/ISO"> example, that
would have gone right over my head :]

Thanks!
