Oops.

If it's construed as an attribute value template, format="{1}" would indeed 
evaluate as format="1". When I tried it with {1} to see whether it was an 
AVT, I just forgot to try {{1}} (good catch). Presumably it's an AVT so you 
can make the number format dynamic.

No, I don't think value has a default.

I agree, rather. Apparently the word "position" is used in its English 
language sense, not its technical sense. Perhaps they could say "based on 
where it is in its containing document" which seems to be vaguer, but 
isn't, and doesn't run the risk of saying what they don't want to say by 
invoking the technical sense. :->

Oh well.

Cheers,
Wendell
