ReqIF export of custom requirement attributes.

[LKA]

Hello,

I have created a generalization of the built in "businessRequirement" class with an additional attribute. How do I get the ReqIF export to include this additional attribute? It appears that the ReqIF exporter will only export "system defined" attributes. In the attached sample project I would like to get the attribute "Supported OS" of the "RequirementProperties" extension of "businessRequirement" to be exported in the ReqIF.

Any thoughts on how to achieve this would be greatly appreciated.
