Essentially because we (but I am NOT speaking officially for the Core WG
here) don't think they carry any real information.  There is no difference
between CDATA sections and careful use of < and &.

We are aware that DOM doesn't really match the Infoset.  It was either
do it DOM's way from the beginning or give up on DOM compatibility.
We chose the latter.
