Can someone respond to this question on dosage? http://community.fhir.org/t/fhir-dosage-timings/3428

Made an attempt.

This is an elegant way to resolve the assertion of an XOR between two dosageInstruction.
I would have preferred an actual ability of the Timing data type to support this exclusive schedule alternative.
This solution, expressing XOR of two dosageInstruction elements by a third one having .method.coding.code=420561004 in the same .sequence is not obvious. Is it validated by the Pharmacy WG (@Jean Duteau) ?

@Olivier Boux I don't know if the suggestion, presented as a possible solution for question 2 in the above community fhir link, is valid according to or has been validated by the Pharmacy WG.
My suggestion came out of much ongoing work in trying to get NCPDP Script 2017071 to fhir v 4 (4.6). And inklings of possibilities from NHS https://developer.nhs.uk/apis/dose-syntax-implementation/dosage-sequence.html . I am struggling with this stuff as well, mostly trying to avoid the escape hatch of extensions.
