I considered this approach a while ago and discarded it. It would work
but it is just too much of a Frankenstein monster.

Much cleaner to modify dtc to take a schema as part of the compilation
process. The schema language itself has no requirement to look like
DTS syntax. Whoever wrote dtc probably has a favorite language that
would be good for writing schemas in.
