#34346 and #34348 applied. Please check if it is OK

For NutritionProduct, I put the biologicalSource under Instance, which is where I think it makes sense. I think the Product pattern should have the same, assuming that biologicalSource is for instances only.

i.e. biological source indicates "This comes from THIS pig" not "contains porcine products"

@Becky Gradl @Marti Velezis @Rob Hausam @Hans Buitendijk @John David Larkin Nolen feedback welcome
Hans Buitendijk (Dec 08 2021 at 16:18):
Agreed.
Still have a problem with NutritionProduct that in the absence of an "instance Boolean", I have no idea whether the resource instance represents a partially completed NutritionProduct instance or definition. But that is a different story. Clearly if any of the .instance attributes is valued it is an instance, but if none are valued I have no clue.

It's the same as medication. And in general, it doesn't matter...

One idea on this last topic raised by Hans:
In practice something that is an instance vs a kind is normally implied by the context.
As long as we have a place to indicate the attributes of the product, we can achieve most functionality with the pattern as it is.
For the scenarios where we want to count parts (i.e. instances) but we don't know any instance info, where we need to say explicitly "this is one instance" we could have that boolean as an extension...
"when true, indicates that the resource refers to a physical instance of the product, not to the kind definition - in which case the resource may be safely appended with other attributes e.g. serial numbers without changing its fundamental nature. It also indicates that the resource should be used to populate "inventory" data structures and not "catalog" data structures.
