I suspect it's because SGML had other kinds of marked section - you
could have a conditional section,
<![%IfNoShoes;[ I am happy today! ]]>
and these could nest.

But the SGML CDATA handling always seemed a little odd to me.

Last time I checked MicroXML did not have attribute value normalization
and was therefore not a strict subset of XML. But maybe that's excessive
pedantry on my part.
