Besides having an error, there is no need to reference this. It is
applied to all nodes and you still have to list the properties here to
define how many entries and what they are.

Need to define what each entry is.

Wow, those are useful names.

Already has a type. Need to define how many entries and what each one is
(if more than 1).
