   The <dfn attribute for=CSSPseudoElement>style</dfn> attribute
   is a <code>CSSStyleDeclaration</code> [[!CSSOM]]
   that allows directly setting style information (inline styles) onto the pseudo-element.

-  The <a href="https://www.w3.org/TR/DOM-Level-2-Events/events.html#Events-EventTarget"><code>EventTarget</code></a> interface [[!DOM-LEVEL-2-EVENTS]]
-  must be implemented by all instances of <code>CSSPseudoElement</code>
-  as a conformance requirement of this module.
+  Declarations set via this mechanism
+  follow the same cascading rules
+  (i.e. those of a <a href="https://www.w3.org/TR/css-style-attr/#interpret">style attribute</a>)
