I thought of this before I gave my previous answer, but I
was concentrating on "applying", and these functions don't
change "applying to", so I think my answer stands.

But you are effectively asking the following question:

  If one has a non-inheritable property on an FO to which that
  property does not apply, and a descendant FO to which that
  property does apply references that property via a from-parent()
  or from-nearest-specified-value() function call, what value 
  is returned by that function call?

I will pass this question on to the group.  The tricky thing is
that these functions return the "computed value" of the property,
and I'm not sure if a property has a computed value if that 
property doesn't apply (but I'm not sure if it doesn't either,
which is why I'll be asking others who are more expert on the
data model here).
