per Jörg's comment: this may need to be addressed by the evolution of the model.

Resolution of this issue is pending a formal conclusion of the discussion on the expression of observedProperty and featureOfInterest, and the mapping to WIGOS code lists, and the business rules for parsing WMDR. Please refer to https://github.com/wmo-im/wmds/wiki/The-idea-and-concept-behind-WMDS and references therein.
