Used to define the value of a key in a type entry of a IndexedStorage.
Valid values are "string", "boolean", "number" and "id:TYPE",
with TYPE being one of the types in the definition.
In the latter case this means that key points to an identifier of the specified type.
A ? can be appended to the type to indicate this key is optional.
