File src/com/google/caja/plugin/html-emitter.js (right):

Line 75: base.innerHTML = htmlString;
As discussed, I'm fine with clobbering, but maybe we could fail fast if
there is content.
Something like
  // TODO: we could append the HTML but no clients need that yet.
  if (base.firstChild) { throw new Error(...); }
