SYSML16 — Derived attribute should also be read only

In the xmi file representing the profile, that can be found here:
ptc/2015-07-05 http://www.omg.org/spec/SysML/20150709/SysML.xmi

The derived attributes should also be set to read-only:
<ownedAttribute xmi:id="SysML.package_packagedElement_Requirements.stereotype_packagedElement_Requirement_ownedAttribute.master" xmi:uuid="org.omg.sysml.SysML.package_packagedElement_Requirements.stereotype_packagedElement_Requirement_ownedAttribute.master" xmi:type="uml:Property">
<name>master</name>
<isDerived>true</isDerived>
...
</ownedAttribute>

In Papyrus SysML 1.1 version, the derived attributes have been set to read-only.
It will be the same for SysML 1.4 implementation. See https://git.eclipse.org/r/#/c/71034/2/core/org.eclipse.papyrus.sysml14/resources/profile/SysML.profile.uml

It would be good to provide for SysML 1.5 either the profile with readonly or specify in the norm what should be implemented for the write access
