The element <partSegment> contains data pertaining to the part, independent of the location. The element <partSegment> is optional as part data can also be stored in the part CIR. Refer to Chap 3.9.5.2.11.3.For an S2000M project, the element <partSegment> partly corresponds to the S2000M part identity segment (PAS). It "partly" corresponds because it has additional information suitable for a non-S2000M project.
