I went googling for XML validators and tried your sample in both forms, as
you sugest with CDATA and my way:
<root>
<data><?php require_once("read_database.php"); ?></data>
</root>
Both are valid. The relevant paragraph can be found in:
http://www.w3.org/TR/2004/REC-xml-20040204/#sec-pi
Notice that while <?php is a valid start tag the shorthand <? is not since
it is missing what the standard calls the Processing Instruction Target, or
PITarget, for short. This PITarget is the application that is supposed to
understand this PI. The XML standard says nothing about the contents and
syntax of whatever is within the PI tags, only that it cannot contain a ?>
