I'd just throw an exception when a LAS file isn't standards compliant
(+1 hard ass).  A separate tool can be written that catches these and
tries to fix up files.  This keeps things clean and gives direct
feedback on naughty LAS files.

If you want to include additional code to handle bad data, it would be
definitely be nice to be have a flag that enables or disables this
behaviour (the strict/loose interpretation Mateusz suggests).

Cheers,

Mike.
