Questions about the Incident object in STIX 2.1

["Jessie\(TWNCERT\)" <jessie@twncert.org.tw>]

Hi Forum members,

We are planning to use STIX 2.1 in our organization and we notice that the
Incident object is reserved.

Due to one of the key missions of our organization is to receive and share
Incident information with our partners, we need the Incident object to share
the information.

It would be appreciated if you could provide us more details and clarify
some of the doubts about the Incident object at the present stage.

1. As Incident object is reserved, we are wondering in which STIX version
would define it? (STIX 2.1.X or 2.x?)

2. We found the document online mentioned the Event object. Is it the same
meaning as Incident object?
