Hi, these properties (issue date, first accrual date) sound like reference data relating to the bond, rather than contractual properties of the option as such – so probably should be modelled as properties of the bond underlyer. The Bond type in FpML does contain a number of optional reference data items (e.g. issuerName, seniority, couponType, couponRate …), however the dates you mention are not currently supported.
You are welcome to propose these Bond properties for addition to the Standard, but that may not help with your immediate requirement. Are you able to add these as local extensions to the Bond type e.g. in a private extension namespace?
I don’t recommend re-using existing elements e.g. relevantUnderlyingDate, other than for their intended purpose.
Best regards,
Harry
