INDEX="primary[/[secondary][/primary[/[secondary]...]]]"
Where primary and secondary are phrases. For example:
INDEX="tags/markup/markup/tags"
INDEX="language/generalized markup/generalized markup/language/GML//SGML"
These might result in index terms that look like these:

As with the HTML+ spec, the INDEX attribute would be used by an index-building
program (which could be a module of a browser) to build an index for one or
more HTML documents.
