Postel's law is often the wise thing to do.
But it is not a panacea. It isn't an excuse for sloppy specifications.

In particular "be conservative in what you send, be liberal in what you 
accept" only works when there is only one liberal and plausible way to 
interpret what you expect. While that is often true it isn't always true.

	Thanks,
