    Subject: [xacml] SH02: Use of decimal math should be justified


    It is unusual to specify the use of decimal math in
    a specification like XACML, especially requiring strict
    conformance to a detailed specification of decimal
    math behavior. Many platforms do not support decimal
    math. Binary math is much more common.
    
    I can see why you might want to use decimal math for
    this specification. Maybe you're likely to be doing a
    lot of financial calculations. Still, I think it's a
    bit odd that you require support for exponents, NaNs,
    and the like in the implementation but don't provide
    any way for a user to access these features. A simpler
    approach would have been to leave the arithmetic
    loosely specified, like XQuery has done.
    
    At the least, I think you should add a few sentences
    to the end of section A.12 Arithmetic evaluation saying
    
      Decimal arithmetic is used in order to provide
      results that closely match those expected by the
      average user.
