[PATCH wayland 0/3] Restore DTD and use wayland-scanner to validate

[Peter Hutterer]

This patchset restores the dtd (and adds a new element "description" to the
<protocol> tag) and adds the validation bits. Since expat doesn't validate,
a second library is used (libxml2). To avoid breakage, it's hooked up
independently of the current parser, so we essentially just parse the input
twice, spitting out a warning if the validation fails.

The dtd is built into the scanner, so we can validate external protocols as
well.

Cheers,
  Peter
