possible inconsistency between xAPI Statemet examples and specification
while working on implementing Rust bindings for the xAPI model types i encountered what looks like an inconsistency in the first two Statement examples [1].
the JSON data of those examples contain an 'object' referring to an Activity without an 'objectType' property. the specification in [2] however states that that property is required.
i would appreciate it if you can clarify whether the examples are invalid, or there is text in the specification i missed that describes when an Activity without its 'objectType' can be used in a Statement.
