[From PmWiki/ConditionalMarkup]

Any (:if:) automatically terminates the previous one, thus markup can be 
easily cased:

    (:if auth read:)* You can read
    (:if auth edit:)* You can edit
    (:if auth upload:)* You can upload
    (:ifend:)

So, you just have to "mix" it with Cookbook/ConditionalExtensions.
