The '&' in character references is converted to & when used in set_attribute
e.g. ! is changed to !

$oXml      = new_xmldoc("1.0");           
$oRoot     = $oXml->add_root("outputXml");
$oRoot->set_attribute("test","&033;");
print $oXml->dumpmem();

This produces 
<?xml version="1.0"?>
<outputXml test="&amp;033;"/>

instead of
<?xml version="1.0"?>
<outputXml test="&033;"/>

PHP modules compiled:
'./configure' '--prefix=/usr' '--with-apxs=/usr/sbin/apxs' '--with-exec-dir=/usr/bin' '--with-config-file-path=/etc/httpd' '--with-regex=system' '--enable-debugger' '--enable-magic-quotes' '--enable-sysvshm' '--with-dom' '--enable-force-cgi-redirect' '--enable-sigchild' '--with-wddx' '--enable-inline-optimization' '--with-gnu-ld' '--enable-bcmath' '--enable-crypt' '--with-xml' '--with-sablot' '--enable-dbg=shared' '--with-dbg-profiler'

You actually ran into a feature of libxml2. It does automatic character encoding. I remember it was discussed to implement a function to set raw attributes but as far as I know the current version it's not implemented so there's little we can do about it (but I would be happy to be proved being wrong here).

Not a PHP bug -> bogusifying.
