Sequence Location: Is type supposed to be the only required field?

In VRS 2.0.1, we see that type is the only required field for a SequenceLocation. Is this correct?

In the docs, it says:

Start, End, and Ranges

At least one of the start and end properties MUST be specified in any SequenceLocation instance. When only one of these properties is specified, this represents an open interval beginning at the specified coordinate and extending left (when start is null) or right (when end is null).

When there is ambiguity at a coordinate (e.g., when using a SequenceLocation to describe the confidence boundary of a copy number segment), this is specified using the Range class for that coordinate.

At least one of the start and end properties MUST be specified in any SequenceLocation instance. Are the docs outdated or is the JSON schema wrong?
