-// This class is used for strings that tend to be shared with JavaScript frequently. The JSC implementation uses wtf::UString - see bindings/js/ScriptString.h
-// Currently XMLHttpRequest uses a ScriptString to build up the responseText attribute. As data arrives from the network, it is appended to the ScriptString
-// via operator+= and a JavaScript readystatechange event is fired. JavaScript can access the responseText attribute of the XMLHttpRequest object. JavaScript
-// may also query the responseXML attribute of the XMLHttpRequest object which results in the responseText attribute being coerced into a WTF::String and
-// then parsed as an XML document.
-// This implementation optimizes for the common case where the responseText is built up with many calls to operator+= before the actual text is queried.
