We have a facility in skinconf for the pelt skin called MOTD "Message of the day". It appends the version number to the html title and puts a little notice on the page and in the menu. This was a quick workaround to make sure that it is obvious which set of docs the user is looking at.
However, with the current demo of the docs-reorg branch: http://people.apache.org/~crossley/docs-reorg/ the same message is shown on every page. I have enhanced the facility to add different messages depending on the URL path. So now we can append different messages to the versioned docs and none to the top-level docs. This is nice. However i have not yet committed this. It needs changes to the skinconf DTD. We have skinconf-v6-3.dtd which already has the rudimentary MOTD elements. This enhanced MOTD will need to change the structure. So it would need to be a new DTD. I propose to call it skinconf-v7-1.dtd and not try to also support the old 0.7-dev behaviour. I will add that to the docs-reorg branch ASAP. -David
