Documentation:
Alist of objects restrictions.

CAR is an element or object type containing objects and CDR is
a list of successors that will be called within an element or
object of such type.

For example, in a `radio-target' object, one can only find
entities, latex-fragments, subscript, superscript and text
markup.

This alist also applies to secondary string. For example, an
`headline' type element doesn't directly contain objects, but
still has an entry since one of its properties (`:title') does.
