Add a copyright.

Done.

We don't want to add these static methods to supplement classes. Instead, the
caller sites should call:

  DocumentXSLT::from(*document).sheetLoaded()

I added the comment:
    // The following static methods doesn't use any instance of DocumentXSLT.   
                           
    // Just they are just using DocumetnXSLT namespace. 

+
+    virtual void trace(Visitor*) override;
+
+private:
+    DocumentXSLT();
+
+    RefPtrWillBeMember<Document> m_transformSourceDocument;
+};
+
+} // namespace blink
+
+#endif
