Adapt syntax help depending of syntax used on the page

I'll be nice to have an adaptation of the syntax help depending of the syntax we use on the page.

Exemple :
Page using xwiki2.0 -> Syntax help concerning xwiki2.0.
Page using xwiki1.0 -> Syntax help concerning xwiki1.0.

In 1.8.1, we have :
Page using xwiki2.0 -> Syntax help concerning xwiki1.0.
Page using xwiki1.0 -> Syntax help concerning xwiki1.0.

Thanks in advance,

Hesediel.
