why aggregation of all properties in xmi files for KerML and SysML are missing

[GazeboXu]

Hello,

I’ve noticed that in the current KerML and SysML XMI files, none of the Property elements have an aggregation attribute. Could you please explain why this is the case?
Also, I found that in an earlier SysML XMI file (https://www.omg.org/spec/SysML/20230201/SysML.xmi), some of them did include this attribute.

Thank you!

It does, indeed, seem to be the case that the latest normative KerML.xmi and SysML.xmi abstract syntax files are missing all aggregation properties. Thank you for reporting this. Amazingly, no one else has noticed it so far.

This does not seem to be a Pilot Implementation issue, though. I have checked the exported abstract syntax .uml files under org.omg.sysml/model, and these do have the expected aggregation properties. So, the problem happened somewhere later in the tool chain for generating the normative XMI. Once we track down how this happened, the XMI will need to be corrected by the KerML 1.1 and SysML 2.1 Revision Task Forces, since these files are normative standard artifacts.

ok, thanks for your reply.
