5.15.0 Beta 1

The 5.15.0 Beta release adds support for mapping fields directly to extension and modifierExtension paths.

For example, see the last two mappings in this DSTU2 mapping:

Observation maps to Observation:
  // ... field mappings here
  ReferenceRange maps to referenceRange
  ReferenceRange.Range.LowerBound maps to referenceRange.low
  ReferenceRange.Range.UpperBound maps to referenceRange.high
  ReferenceRange.Type maps to referenceRange.meaning 
  ReferenceRange.ApplicableSubpopulation maps to referenceRange.modifierExtension
  ReferenceRange.ApplicableAgeRange maps to referenceRange.modifierExtension
  // ... more field mappings

The above would create extensions for ApplicableSubpupulation and ApplicableAgeRange and then map them as modifierExtensions on Observation.referenceRange.
