Labeled Section Transclusion
This extension allows selective transclusion of marked-off sections of text, i.e. it allows users to transclude only a part (or multiple parts) of a page on another. Unlike normal transclusion, it is possible to transclude different parts of the same page on other pages.
This extension allows editors to use programming-language-style variables on wiki pages. It is possible to define a variable on a page, use it later in that same page, change its value, possibly to a value given by an expression in terms of the old value, etc.
This extension provides some common blogging features; it is used for The Vault's news system. Among the features added by the extension are: automatic listing of articles, setting of article authors, handling of article comments, generation of syndication feeds (Atom and RSS) for individual wikilogs and for all wikilogs of the wiki, etc.
