* Namespace definition maps a namespace URI to a prefix name. For example:

* <pre>
* @namespace s "library://ns.adobe.com/flex/spark";

*
* The {@code @namespace} directive maps "library://ns.adobe.com/flex/spark" to
* prefix "s". The selector can be gated with "s" to style "spark" components,
* like {@code s|Button} .
* <p>
* Every CSS document can have a default namespace definition without specifying
* a prefix.
*
* <pre>
* @namespace "library://ns.adobe.com/flex/mx";
* </pre>
*
* Then all the type selectors without a namespace prefix defaults to components
* in the default namespace.
