-ECMAScript for XML (E4X) comprises XML markup and XML data manipulation facilities.
+ShockScript for XML (S4X) comprises the XML capabilities of the ShockScript language.
 
 ## Markup
 
-XML markup is directly used in ActionScript for rendering reactive user interface.
+XML expressions by default are used for building implementation-defined objects; however, when the inference type is `XML` or `XMLList`, XML expressions result in one of these types.

-> **Note:** Unlike the E4X standard 2nd edition, markup does not result in `XML` or `XMLList` objects, but rather `ReactNode`; and there is support for `a` attributes without an attribute value, which equals `a={true}`.
+### Attributes

 ## Events
 
 Events are declared without defining related static constants, as ShockScript performs vast type inference; thus, the ASDoc `@eventType` tag does not exist in ShockScript.
