No that's actually not a good way. Marking an article that is for this or that version doesn't help match. It can be easily missed.
Best way is to have documentations for each branch so you can choose the branch - 5.3.x, 5.4.x, etc - and all articles related to it are in there. Of course for this to work we have to have a documentation first which is lacking big time with XC5 at the moment.
