ImportsMasterDocument maybe? :)

I'd keep Document concept away.
But you're right. It'd better to pick terms from the spec.
I'll rename this to HTMLImportsMaster.

 public:
-    PassRefPtr<CSSValue> toCSSValue() const;
+    virtual ~HTMLImportsHost() { }
+    virtual void didLoadAllImports() = 0;
+    virtual SecurityContext* importsContext() = 0;
 };
 
 } // namespace WebCore
 
-#endif // AnimatableValue_h
+#endif // HTMLImportsHost_h
