Incorrect FHIRPath in Consent Australian Organ Donor Register inv-dh-cons-01 and -02 #5
[x] I have verified the problem exists in the available content
[x] I have searched open and closed issues to make sure it isn't already reported
[x] I have written a descriptive issue title
The bug
The invariants
inv-dh-cons-01: If donation decision is 'permit', there SHALL be a specific organ (except.data.reference).
and
inv-dh-cons-02: If donation decision is 'deny', there SHALL NOT be a specific organ (except.data.reference).
fail for valid examples. In the FHIRPath expressions the antecedents are always true, so e.g. an instance with donation-decision of 'permit' and with a specific organ (except.data.reference) will fail with an error against inv-dh-cons-02.

What I expected to happen
Correct the FHIRPath expression:
