If you really wanted an EndSection why not just repeat the section name?

BeginSection "news"
EndSection "news"

A bit verbose, but if you want an EndSection you don't really care
about being terse anyway. :)

You'd get yourself a bit of error checking too, if somebody were to
leave a section unclosed or attempt to close the wrong section.
