[GeoSciML] GeologicEvent bounded by boundaries instead of ages ?

We are trying to create a mapping between datasets and GeoSciML vocabularies and we started wondering why GeologicEvent is bounded (olderNamedAge and youngerNamedAge, or olderGeochrologicalAge and youngerGeochrologicalAge in GeoScimLExtension)  by Age (a name from a vocab for basic or TimeOrdinalEra for extension) instead of boundaries ?

Wouldn't it be more coherent to limit a event by two boundaries (TimeOrdinalEraBoundary), eg: isc:BasePhanerozoic and isc:BaseSiluria for a Cambro-Ordovician unit. ?
  TimeOrdinalEarBoundary has subtypes for numerical and Geochron boundaries.
