Which may - at least in part - be caused by the fact that non-native
speakers have written bigger sections of the documentation. In German
"to refer to" would be "referenzieren" which translates to "to
reference to" in my brain.

Yes, although there are other tasks that create properties as well.

Yes.

Not necessarily. A "type" is anything that has been declared via
<typedef>. Creating instances of types and referring to them by id is
a common usage of types but not the only one.

True. But note that <antcall> reevaluates the same buildfile and may
see references to different objects if they have been declared at the
top level.

Yes.
