Thanks for explaining Markus.
The advantage of avoiding "equivalentProperty" in favour of "subPropertyOfExternalProperty"
(and similarly for classes) is also that our definition can be more specific than the one used for the external property/class. So we can relate our data to multiple external things, which may fit our own definition more or less tightly.
Agreed.
