+The 'name' attribute of the 'a' element is a depracated way to create a named anchor. The right way to do that is using the 'id' attribute of any element. This is because an anchor may refer to a complete element rather than some point in the page.
+
+Standard purity aside, if you define an anchor (using either 'a name' or 'id') to a single point in the document but refer to a complete section, the browser may just show that specific point at the bottom of the page rather than trying to show all the section.

+
+I like your suggestion because it's short and conscise. However, it would be nice to be able to refer to more or less arbitrary meta tags in links, not just "title". To do that, the link needs two parameters: the page name and the tag name, i.e. \[[pagename!metatag]]. Any sufficiently weird separater can be used instead of '!', of course. I like \[[pagename->metatag]], too, because it reminds me of accessing a data member of a structure (which is what referencing a meta tag is, really). --Peter
