Reviewing Capabilities I noticed that in Yum: Generate Metadata and Yum: Staging Generate Metadata that the Aliases field had helper text "Format: =[,=]".
I had no idea what this meant and after reviewing the book at Manfred Moser's prompting, I found that it means that the Aliases field is comma delineated (i.e. production=1.2,testing=2.0).
Even knowing this, I feel this is unclear. Suggest we replace with that fact or just put an example (either in helper text or in greytext in the field itself).
I did not check older versions of NX3 at this time.
