Where can I find the expression language specification?

1

Most of the profiles out there, have some type of non structural rule expressed in terms of:

  • hasValue()
  • exists()
  • contains()
  • all()
  • empty()
  • implies
  • …

Where can I find the specification of such expression language?

Thanks.

Is there a parser for FHIR paths in HAPI FHIR?
