Also, the feature is not scheduled for deletion any more, as I have found a decent way to make it work again with the new architecture of the development version of the tool.
]]>One tiny note: http://www.w3.org/2002/08/extract-semantic is the URI of the XSLT used for the extraction of semantic information (including outline). It is decently presented via CSS to most browsers, but for browsers without XML styling capabilities, it looks a little bare. http://www.w3.org/2003/12/semantic-extractor.html is a plain HTML frontend to the same tool, it may be interesting to link to that instead.
