My suggestions for the additional text:

 

Change in current draft from:

Preservation Description Information (PDI): The information, which along
with Representation Information, is necessary for adequate preservation of
the Content Data Object and which can be categorized as Provenance
Information, Context Information, Reference Information, Fixity Information,
and Access Rights Information.

Note: Defining PDI (as well as its components - Provenance Information,
Context Information, Reference Information, Fixity Information, and Access
Rights Information) as relevant to the Content Data Object does not mean
that those concerns are any less important for other data objects or at
other levels, for example, it is important to apply reference, fixity,
provenance, context and access rights to Representation Information, or to
any other information the Archive is preserving. Definition of these terms
as relevant to the Content Data Object is simply to ease discussion of these
concepts at the Content Data Object level.

I suggest deleting the last sentence because it does not make sense to me.

 

Change

 

Content Information: A set of information that is the original target of
preservation. It is an Information Object composed of its Content Data
Object and its Representation Information.

To

Content Information: A set of information that is a the original target of
preservation. It is an Information Object composed of its Content Data
Object and its Representation Information.

There are a few other places the change "the original" to "a" would also be
needed.

 

Add to the end of section 4.2.1.4 Taxonomy of Information Object Classes
Used by OAIS

Content Information is any Information Object which is being preserved by
the Archive. 

 

I don't know an easy way to put this into the UML diagram.

 

Also add the end of section 4.2.1.4.1 Content Information: 

Any Information Object being preserved by the Archive, such as
Representation Information, PDI etc., may also be considered to be Content
Information.
