No, it's not. It's an unmaintained relic waiting to be deleted. I
suppose it has remained as an informational reference.

It was once written for running the XML files through xmllint because
wayland-scanner rather crashed than complained about bad XML. The
xmllint phase was since removed on the basis that wayland-scanner is
our definition - if we need more errors, we should enhance
wayland-scanner.

See:

The DTD has never specified the semantics, like Victor points out.
