I suspect it's using output method html rather than xml.

I can't quite remember why the serialization spec says (in 7.2)

"The HTML output method MUST NOT escape "<" characters occurring in
attribute values."

but I'm sure it was a good reason!

However, the output here is clearly neither XML nor HTML, but some other
angle-bracket-markup-language, and the best way of producing output in an
ABML that is neither XML nor HTML is usually to use character maps as Ken
suggests.
