Hi Bob:

   But I think, they intended the "FO" processor to evaluate the
function, not the XSLT engine.  If  I do the curly braces, then
the XSLT engine will evaluate the expression, then a number (with
a unit) will be passed to the FO Processor.  I guess the question now
is which processor the specs. intends to evaluate the expression?.

The reason I am confused is because the example given inside section
5.10.1 uses units inside the function's argument which is giving
the FO processor a real hard time.

Greetings,
Carmelo
