Well said.
In the IETF world, this is called "be lenient in what you
consume, be strict in what you produce".

Failure to correctly document what producers should produce
risks creating a language over time where the sheer bloat created
by exception handling rules will paper over the actual language
--- and by the way this did happen in the 90's during the heyday
of tag-soup browsers; over time, browsers could render malformed
content, but not well-formed content.
