Throughout Clause 13 "Evidence", and in the metamodel, namely in the Evidence and Risk package, the word "Artifact" is misspelled as "Artefact". Correcting this will implicitly correct also a discrepancy with SACM.

Update the text of Clause 6.2 "Intellectual Property Rights" to ensure unrestricted world-wide access to the specification at no cost. The OMG IPR rules and the recorded copyrights shall apply.

Unfortunately SACM removed the explicit Artifact Citation element at some point in its revision history, which breaks backward compatibility. A solution for the use of citation in the PSUM Evidence and Risk package would be a specialization of the SACM ArtifactReference metaclass, then subsetting the reference pointing to referenced Artifacts to point to the cited Artifact

The PSUM specification defines a MOF metamodel for the modeling of uncertainty. However, the Associations in this metamodel are not named, which is a requirement for MOF models.

This issue was actually raised by the designated reviewer form the OMG Architecture Board. His argument was, that "Risk" is too broad for risk resulting from uncertainty.

In some diagrams of the metamodel, element names are underlined, or part of the diagram elements have shadows and others not, enumerations have unnecessary color.

In Clause 6.1.1, the use of italic font to designate model element names in the text is mandated. This is not consistently applied throughout the document.

There are many places in the document where sentences read similar like "We decided to define ..." or "therefore we defined ..." (maybe not exact quotes, but demonstrating the style). These sentences need to be rephrased to read as expected in a standards document.
