Agreed. I recall from my own experiments (long ago) with template that 
the defaults-in-definitions were troublesome. I think I ended up not 
using them at all.

I'm generally not keen on automagic stuff myself, but that's just me.

One remark without having looked at template-alt in detail is however 
that the signatures above feel as though they're on the wrong side of 
the =. That there are two arguments is a property of number-format; you 
need to know this when providing a value for this parameter. The :N 
signature rather seems like it applies to the implementation, the 
details of which are otherwise in the right hand side.
