How would the API look like ? Should validation be on for parsing / dom
manipulation whenever a dtd is attached to the document and ommitted if
not ?

Alternatively, should the document have a flag indicating whether
modifications should be audited ?

Or should each modifying call get an additional bool parameter to
indicate 'do validate' ?

I guess we all agree that the last is not really an option. I tend to
think that the first (validate whenever a dtd is present) is best, at
least as the default behavior, while a 'suppress_validation()' method
could be used if the user wants not to validate.
