Well, maybe. XML doesn't require you to escape '>' in text, only in
attribute values.

Presumably, in order to calculate the referencing, one would need to know
precisely how this string was to be serialized? Does that mean it needs
to... what? Hardcode that knowledge based on the library used? Seems
astonishingly fragile, especially if you're working in an environment where
the XML serialization is provided by the platform. Like a web browser.
