I will look into it.

Regarding the definition of derivation, "a transformation of an entity into
another, an update of an entity resulting in a new one, or *the
construction of a new entity based on a pre-existing entity*", it is clear
that this case is not a transformation or an update of an entity into
another. So we are discussing the third part (highlighted). My concern here
(and Michael's) is that stating a derivation is kind of contradictory. What
if the text was "The construction of this document (Doc1) was not based on
REF 1". Stating the derivation would imply exactly the opposite. Derivation
is too strong in this case, don't you think?.

Best,
Dani
