And you wanted to do Av_Param_Instance'Access inside the generic?

That won't work, because the compiler can't check the rules about
X'Access, because it doesn't know enough about the actual parameter
passed to Av_Param_Instance.  The accessibility rules come to mind.
Also, the fact that you can't do X'Access if X is intrinsic.
