Section 3.6 says:

Security Context Id:
 This field identifies the security context used to implement
 the security service represented by this block and applied to
 each security target.  This field SHALL be represented by a
 CBOR unsigned integer.  The values for this Id should come from
 the registry defined in Section 11.3.

It should say:

Security Context Id:
 This field identifies the security context used to implement
 the security service represented by this block and applied to
 each security target.  This field SHALL be represented by a
 CBOR unsigned or negative integer.  The values for this Id should
 come from the registry defined in Section 11.3.

Notes:

Per the IANA sub-registry in Section 11.3 the Context ID has "The value range: signed 16-bit integer." and negative values are reserved for private use, so the value can be either an unsigned or a negative integer.
