The problem with this statement is that it is not a Language Design Principle.
It is a User Agent Design Principle. I would feel more comfortable if you
would label it as a User Agent Design Principle.

I think that a Language Design Principle could be something like the following:

SupportExistingContent: The HTML WG will document the usage of HTML
as it is practiced by popular web browers, and deployed on the web and on
intranets throughout the world. Our goal should be to facilitate understanding
