+// GENERATED PREAMBLE - DO NOT EDIT
+// CSSOMString is an implementation-defined type of either DOMString or
+// USVString in CSSOM: https://drafts.csswg.org/cssom/#cssomstring-type
+// For web-platform-tests, use DOMString because USVString has additional
+// requirements in type conversion and could result in spurious failures for
+// implementations that use DOMString.
