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

Resolve connection to SACM 2.3

A revision of SACM had removed the explicit citation modeling. To overcome this backward-incompatible change in SACM, the PSUM submission substituted the missing ArtifactElementCitation element in a stub model. This resolution corrects the situation by moving ArtifactElementCitation to the PSUM Evidence and Risk package, and make it specializing ArtifactReference of SACM. The change is purely in the PSUM Metamodel, but will also affect Clause 13 and Figures 8.1 and 13.1

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.

Rename "artefact" to "artifact"

In Clause 13 "Evidence", and in the PSUM Metamodel, the word "artifact" is misspelled as "artefact". Besides linguistics, this causes also reference problems between PSUM and SACM. Correcting the spelling resolves the references too.
