   present, then the user agent must apply the specified style

+  an editor can be found to own this.</p>
+
+  <p>Within scoped CSS resources, authors may use an <code
+  title="">@global</code> @-rule. The syntax of this rule is defined
+  as follows.</p>
+
+  <p>The following production is added to the grammar:</p>
+
+  <pre>global
+  : GLOBAL_SYM S* ruleset
+  ;</pre>
+
+  <p>The following rules are added to the Flex tokenizer:</p>
+
+  <pre>B                     b|\\0{0,4}(42|62)(\r\n|[ \t\r\n\f])?
+@{G}{L}{O}{B}{A}{L}   {return GLOBAL_SYM;}</pre>
+
+  <p>Simple selectors in rule sets prefixed by the <code
+  title="">@global</code> @-rule in scoped CSS resources must be
+  processed in the same way as normal rule sets in non-scoped CSS
+  resources.</p>
+
+  <p>Simple selectors in scoped CSS resources that are not prefixed by
+  an <code title="">@global</code> @-rule must only match the
+  <code>style</code> element's parent element (if any), and that
+  element's descendants.</p>
+
+  <p>For scoped CSS resources, the effect of other @-rules must be
+  scoped to the scoped sheet and its subresources, even if the @-rule
+  in question would ordinarily apply to all style sheets that affect
+  the <code>Document</code>. Any '@page' rules in scoped CSS resources
   must be ignored.</p>
 
   <p class="example">For example, an '@font-face' rule defined in a
   scoped style sheet would only define the font for the purposes of
   font rules in the scoped section; style sheets outside the scoped
   section using the same font name would not end up using that
   embedded font.</p>
