Let's say it's application-dependent.  If the light-weight client
cared enough to validate, presumably it cares a lot about (b) ...
else why bother to validate?

This is an issue I wish I'd highlighted in that review, though it
comes out pretty quickly when you look at the raw testing results.
Oh well, next time -- analysing that much data on a dozen parsers
was no small task!

Did anyone mention size?  Size should be an issue too.  All other
things being equal, smaller means fewer lines for bugs to nest in.
