To make it explicit. The generic component system shouldn't impose
(m)any assumptions on version numbering. Version numbers can contain
digits, punctuation, letters. Comparisons should be done the way "ls
-v" and "sort -V" do it.

Whoever creates B-1.1 ought to make it backward-compatible, but he
should also say so. The majority of developers are careless about
backward-compatibility; having the component system make wishful
assumptions will lead to catastrophic consequences.
