Frankly - I did minimal change here that gave me the desired effect on URL composing. When
I write for scratch I encapsulate them in a separate attrSet

>They could be called just ‘name’ and ‘version’, too.

I learned the hard way that all the snippets that are used in the URL give slightly less typos 
when kept separate.

>Are these attributes used by your auto-update tool?

Not yet - all the packages I really try to track are still in the older style
