The $deqm.evaluate-measure IN parameter "measure" is 0..1 and says "This parameter is only required when the operation is invoked on the resource type, it is not used when invoking the operation on a Measure instance"

However, the URL for the operation only lists:

URL: [base]/Measure/$deqm.evaluate-measure

To support not including a "measure" parameter, the below URL should also be listed on the operation page:

URL: [base]/Measure/[id]/$deqm.evaluate-measure
