I'm asking you to make a statement of fact, not to explain how the fact 
was derived. so you could say "this syntax which are largely compatible 
with popular implementations because it is largely based on Internet 
Explorer 6's behavior."

It's important to document history here: without it, we are bound to 
make the same mistakes again. If other implementation played a role 
(e.g., the way Google's spiders process pages), then those should be 
documented too.
