Non null ContinuationToken json but null token value #119

When querying with pagination for partitioned collection, for the last page, the pagination token is not null, but the token field is null. e.g.,

{"token":null,"range":{"max":"05C1D9CD673398","min":"05C1C9CD673398","isMinInclusive":true,"isMaxInclusive":false}}

Does above token indicate it's already the last page? Though in my case, it's actually the last page, besides the whole json itself is not null.

Similar issue here:

The explanation was:
"As for why the SDK does not just give a json null value for the continuation token: The SDK has reached the end for a given partition but mstill needs to visit other partitions to know for sure that there are no more documents that match your filter / need to be returned to the client."

But it's unclear whether should the user treat this as last page. Andrew Liu (@aliuy)
Any help?
