RE: FpML-VAL cd-26 unhandled case

[Matthew D Rawlings <matthew.d.rawlings@xxxxxxxxxxxx>]

I concur with the comments.

We could add a guard to ird-14 to restrict it to effectiveDate, but we could alternatively add support for relativeEffectiveDate. The only problem with relativeEffectiveDate is that we cannot support evaluating relativeEffectiveDate when relativeEffectiveDate/dayType exists because we need calendars to evaluate dayType.

//dayType is of type PeriodEnum. Why is PeriodEnum a restriction of xs:token rather than xs:NMTOKEN? Shouldn't all the enums be restrictions on xs:NMTOKEN?

Matthew,

if the rules need to be complete with respect to optionality, you'll 
find quite a few others where this is not the case - because they were 
not originally written with that in mind.

For example ird-14:

terminationDate/unadjustedDate gt effectiveDate/unadjustedDate

A swap might have a relativeEffectiveDate instead of effectiveDate... 
Anybody got a fine tooth comb handy?
