Same wording as used for this in code system validate code:

The In Parameter "abstract" documentation is very confusing and needs to be clarified or perhaps a better approach instituted. The doc:

if true, then an abstract code is allowed to be used in the context of the code that is being validated. Typically, abstract codes are allowed to be used in value set specifications (e.g. any code that is subsumed by an abstract code), but not in an actual recrod. If false (which is the default value), then only concrete codes as defined by the code system are allowed.

1) It is very unclear what is meant by "...an abstract code is allowed to be used in the context of the code that is being validated." There is not a good reason to differentiate this operation based on the code system designating a concept as "abstract". Few code systems (other than HL7 ones) do this and the concept is a valid member of the code system in any case. If a user wants to know a propert of the concept (such as "abstract" then they should obtain that information using the $lookup operation. Given my understanding I think this parameter should be removed.

2) a typo exists record. should be record
