Yes, it seems wise to push for utf-8 and utf-16 encodings since they are
the most interoperable...

That depends if you want to define a real subset of XML, i.e. if a
2SimpleXML document needs to be a well formed document.

The benefit if you do so is that you'll be able to process 2SimpleXML
documents through any XML tool.

If you want to keep this compatibility, you can't accept "/<" which
isn't well formed.

Why not keep the XML way to escape these characters (&lt; and &gt;)?
