-#### Collections
-
-The value represented by "Type" can also be a [Collection][COLLECTION], a class that contains a list of keys with
-values. Collections can be denoted using a format derived from Generics in Java, as such aptly named Generics-style
-notation.
-
-With Generics-style notation, it is REQUIRED to specify a class name or the array keyword, followed by the type of
-the values enclosed with angular brackets.
-
-Example: to indicate that this element returns an object of class ArrayObject that only contains a series of strings:
-
-    @return \ArrayObject<string>
-
-The type of the values in a Collection MAY be another array and even another Collection:
-
-    @return \ArrayObject<\ArrayObject<int>>
-
-A Collection MAY optionally define the type of the keys of said Collection by adding an additional type definition
-between the angular brackets before the identifier denoting the values' type. These two should be separated by a comma.
-
-Example: to declare an ArrayObject collection containing a list of strings with integer keys:
-
-    @return \ArrayObject<int, string>
-
-The type of a key or value MAY consist of several different types. This can be represented by separating each
-individual type with a vertical bar sign between the angular brackets.
-
-    @return \ArrayObject<string|bool>
