Pedantic addition - escape > when it appears in the plain text outside

this is still true for HTML 5, though, and Web browsers probably don't

Incorrect handling of CDATA sections, especially in generated markup,
is a rat's nest for another day [1] :)


CDATA doesn't meaningfully exist in the HTML syntax any longer, so that's
not a concern. Insert raw > characters as your heart desires!
