{ and } are special characters in E4X for interpolating computed values, e.g. <x>foo</x> is equivalent to <x>{"foo"}</x>, so we should be converting the braces to entities here.

How is bug 497149 a dupe of this bug? It looks like this bug is just about escaping curly braces. Bug 497149 is about "\\n" being put in processing instructions' .toString() output instead of "\n".
