For .src and .id, IE and Opera set "null".
Opera does the same for textContent.

For .src, this obviously means that IE and Opera will then return the
directory of the page + "null" where as FF will return the URI to the
page.

The way IE and Opera do "null" doesn't seem to be just limited to innerHTML.
