Simply because this is the classical OO philosophy (allowing for the
pragmatical distinction between object and value). But also, because
class diagrams are a successor of ER diagrams, and the term "object"
has replaced the term "entity".

Having a sufficient understanding of these general issues, I don't need 
such a reference. But if you need one, I can look it up for you as soon
as I'm back in the office (in 10 days, only, since I'm currently on
holidays:-).
