It's trickier than this -- for example, we'd probably have to create
an exception that is thrown if the underlying parser does not support
validation; furthermore, none of the parsers that I've looked at
supports a toggle like this, and we will be forcing another design
decision on them if we require this toggle.

It might be simpler, though I'm trying to keep the number of methods
to a minimum.  It wouldn't affect EntityHandler.resolveEntity(),
though, since that does not exist solely for the sake of handling
public identifiers.

Thanks, and all the best,
