Subject: Re: FpML-VALID Points Multiplier in FX
One possibility, instead of a decimal <pointsMultiplier>, would be to have
an integer <pointsShift> (??) element where the integer value indicates
how many places to move the decimal point left or right. That would
remove any need for any kind of facet. Is that an option, or is this
already baked into the Schemas? I don't know the history.
An enumeration could be applied to <pointsMultiplier>. It should be
possible to enumerate all of the likely values (and a few more at each end
of the range for safety).
Or, two patterns could be applied to the value (in a simple type with two
patterns, the two patterns are OR'd together). One pattern would be for
values >= 1: 10*
The other pattern would be for values < 1: 0\.0*1
Cheers, Tony.
