For reasons of providing a minimal core language model that could be reused,
less essential functionality is split in the language model API to be provided
by an implementation of javax.lang.model.util.Elements.
So if you subclass JavacTestingAbstractProcessor files that test directory, you
could use
eltUtils.getOrigin(elementForParameter)
to see if an element is marked as javax.lang.model.util.Enum
Elements.Origin.{MANDATED, SYNTHETIC}.
Many of the annotation processing tests use a pattern of using a
runtime-retention annotation to encode what the expected answer is. In this
case, I'd recommend a method/constructor annotation to hold the expected origin
of the parameters.
(The annotation processing API does filter out some SYNTHETIC constructs, but I
don't recall if that is done at a parameter level.)
