Good stuff. Especially the Policy Control Structures. My concerns simply are that the IETF should not be specifying the actual standards for use inside this. Those must be approved and supported by those that use them. For instance there are a number of non-public crypto services which will want to be interchanged with these, to do that the selection of the crypto type needs to be interchangeable.
Also in the MOTIVE section there are several statement's which create specific requirements in the use models, but the use models are missing, so I would suggest changing the two key control statements in the MOTIVE section so they are not specific to "MUST DO" without defining what it is that must be done.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Long-Term Archive and Notary Services Working Group of the IETF.
Title : Data Structure for the Security Suitability of Cryptographic Algorithms (DSSC) 
	Author(s)       : T. Kunz, et al.
	Filename        : draft-ietf-ltans-dssc-06.txt
	Pages           : 41

Since cryptographic algorithms can become weak over the years, it is necessary to evaluate their security suitability. When signing or verifying data, or when encrypting or decrypting data, these evaluations must be considered. This document specifies a data structure that enables an automated analysis of the security suitability of a given cryptographic algorithm at a given point of time which may be in the past, at the present time or in the future.Conventions used in this document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
