Status: Verified
Type: Technical

Reported by: Ladislav Lhotka <[email-masked]>

Section: 7.16.2

Original Text
-------------
An identity MUST NOT reference itself, neither directly nor indirectly through a chain of other identities.

Corrected Text
--------------
The derivation of identities has the following properties:

o It is irreflexive, which means that an identity is not derived from itself.

o It is transitive, which means that if identity B is derived from A and
   C is derived from B, then C is also derived from A.

Notes
-----
The desired properties of identity derivation are not clearly stated. The discussion in the NETMOD mailing led to a general agreement that identity derivation is supposed to be irreflexive and transitive. These two properties together also eliminate the possibility of a circular derivation.
