Inconsistencies between documentation and schema

[franklin-ross]

According to the docs the group field is allowed to be null but in the schema it appears to be non-nullable.

Found another few fields in the docs (listed earlier) but not the schema for group steps.

In the docs but not the schema: allow_dependency_failure, notify

I'd also love to know what the expected behaviour is for the fields that alias each other. What happens if I specify more than 1 and they have different values?

• group, label, name
• key, id, identifier

Another thing is steps which is required, but not defined as required in the schema.
