The {basebackend} attribute is defined in the configuration for the
backend, eg xhtml-11 defines basebackend=html.
But to allow the user to define the backend in the file, the
configuration for the backend is not loaded until after the header is
parsed and attributes calculated, so basebackend is not set during the
header.

The "official" way is to teach your toolchain to add the dot, so you
don't have to remember it. If you find teaching the toolchain too
much of a pain and want to continue this way you could test backend,
it should be defined in the header. Or define td on the command line
as empty or dot in your makefile/build script.
