Section 6.2 says:

Since the Observe Option MAY use a RST message to inform a server
that the client does not require the Observe response, a specific
SCHC Rule SHOULD exist to allow the message's compression with the
RST type.

It should say:

Since the Observe extension MAY use a RST message to inform a server
that the client does not require the Observe response, a specific
SCHC Rule SHOULD exist to allow the message's compression with the
RST type.

Notes:

A RST message is not used by the Observe option itself, but by a CoAP client when using Observe.

The authors wrote:
"[Ana] as soon as I understand CoAP RFC7252 uses Options, and in the
RFC7641 Observe is also an Option, so I don't think that the change is
needed. Because Observe is not an extension."
