Work item link of type Add MVS Members...
I have RTC and RDz installed in the same Eclipse shell with the RTC/RDz integration feature. I recall that way back when there was a way to create a link to an MVS resource from within a work item but although I still see that link type when trying to add a link to a work item, I didn't find any documentation about what the URI format that RTC is asking for should be. Is this feature no longer supported? If so, you should probably have it removed from the UI.
