Robert-
Is it possible to use HTML <a name=""> and <a href="#"> type tags or something similar in a Wikipedia article?
It has been discussed, but I think the majority does not want it, because it complicates linking unnecessarily. It would be difficult to keep track of links to non-existent sections and to fix them, and this might happen a lot given how often articles are rewritten.
What I, and I think most people, would find useful is an option to have an automatic table of contents for every article with more than x headlines (I would say x=3), which would use the headlines as position points for <a name=".."> tags. But you could not directly link to one of the sections from another article.
Actually, you can see a similar feature in action on Sun's Javapedia: http://wiki.java.net/bin/view/Javapedia/AlwaysUseStringBufferMisconception (Die, CamelCase!)
