+Default off. If JSON is embedded in an HTML document and the JSON contains C<< <html> >>,
+C<< </html> >>, C<< <script> >>, C<< </script> >>, C<< <!-- >>, or , C<< --> >> tags, they are
+split apart with a quote, a +, and a quote. This allows the embedded tags to not affect
+the currently playing JavaScript.
+
+However, if the JSON that is output is intended for deserialization by another non-javascript-engine
+JSON parser, this splitting behavior may cause errors when the JSON is imported. To avoid the splitting
+behavior in these cases you can use the no_tag_splitting flag to turn off the behavior.
