These are three IE functions that we would like to implement. Currently we only have insertAdjacentElement but not insertAdjacentHTML or insertAdjacentText, and it just so happens that http://www.openwebware.com/products/openwysiwyg/demo.shtml checks for the existence of insertAdjacentElement and if found, assumes insertAdjacentHTML and insertAdjacentText exist too. So the site fails because the functions are missing.
