 * Hi, I get such error after validating pages with the ASL from W3C as
 * **Bad value** [http://www.w3.org/1999/html](http://www.w3.org/1999/html) **for
   the attribute** xmlns **(only** [http://www.w3.org/1999/xhtml](http://www.w3.org/1999/xhtml)**
   permitted here)**.
    from <style type=”text/css” xmlns=”[http://www.w3.org/1999/html”&gt](http://www.w3.org/1999/html”&gt);
   and warning **Attribute** xmlns **is not serializable as XML 1.0.** From </style
   ><style type=”text/css” xmlns=”[http://www.w3.org/1999/html”&gt](http://www.w3.org/1999/html”&gt);
 * Please fix it.

 * Hi!
 * I can’t see any reference to plugin html in this error message. Is there any 
   more detail about the problem, or which lines of output is causing it?
