CDATA sections in W3C XML Infoset

Could someone explain to me why CDATA section start/end markers were
taken out of the W3C Infoset?

I was hoping to use the Infoset in writing the spec for XML Script,
but the removal of these markers makes it very difficult to write an
implementation of XML Script which is based around a DOM. Dealing with
blocks of text which run across boundaries between text and CDATA
section nodes is quite difficult. It is difficult enough when it
comes to _selecting_ nodes using XPath. It is even more difficult when
it comes to _setting_ node values (something that XML Script allows).

Is there any chance that CDATA section start/end markers could be put
back in?
