I needed to do something similar. I assume you want to prevent security 
bypasses from the untrusted content.

My eventual solution was far from elegant but worked OK: to create a 
"data:" URL containing the encoded form of the document, then to use 
document.getElementById("xxx").webNavigation.loadURI with that URL.

This might also be of help:
