XML Torture Test: Parsers Fail

I agree with the latter myself. Once again, sorry for the late
contributions, I just got back from my so called vacation (in which the
weather totally sucked until I came back :-)

I could see the utility in having a specific flag on your implementation to
force such 'heavy' validation, but I would argue against being forced to
scan it if its not even referenced in all cases. It would be  a nice tool
for DTD developers to use before putting out the DTD.

But I probably wouldn't want my file, which only used 10% of some heavy
duty DTD/Schema, to have to pay the cost to fully validate the DTD/Schema
every time I used it, just to make sure for the one millionth time today
that it was fully correct.
