Can anyone please explain the purpose of the

   @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */ 

css code, which is often recommended to head any userchrome.css text inside the chrome folder? What happens when you omit this @namespace url line?

Is it simply an advertisement for Firefox XML User Interface Language?

You use this line to set the namespace for the code on that page.

Why does one need to set a namespace?? What happens if it is not done?

Good to know it is safe to leave that namespace line out of my userchrome.css code.
