not implemented

=head1 BUGS

This parser becomes exponentially slower as the size of ECD data
increases.  busybox.ecd takes 30 seconds to parse.
Don't even try to parse linux.ecd -- it will sit there for hours
just sucking CPU before it ultimately fails and gives you back
nothing.  I don't know if there's anything I can do about it.

I have noticed that XML::Parser (which wraps around the C library,
expat) is 60 times faster than my Parse::RecDescent-based parser
when reading busybox.ecd.  I really want to take advantage of this.
