+Wiki text block rule for assigning classes to paragraphs and other blocks. For example:
+
+{{{
+{{myClass{
+This paragraph will have the CSS class `myClass`.
+
+* The `<ul>` around this list will also have the class `myClass`
+* List item 2
+
+ }}}
+}}}
+
+Note that the opening and closing braces both must be immediately followed by a newline.
