SYSML17 — Artifacts and «document»

the statement from v. 1.5 (section A.2)

SysML provides the capability to represent a document using the UML 2 standard stereotype «document» applied to the artifact model element. Properties of the artifact can capture information about the document. Use a «trace» abstraction to relate the document to model elements. The document can represent text that is contained in the related model elements.

was removed from 1.6... but 1.6 retained Artifact in its UML4SYSML set...

I think, either remove Artifact or put the statement back in
