+      <para>
+       Using PHP Constants outside of PHP, like in <filename>httpd.conf</filename>,
+       will have no useful meaning so in such cases the <type>integer</type> values 
+       are required. And since error levels will be added over time, the maximum
+       value (for <constant>E_ALL</constant>) will likely change. So in place of
+       <constant>E_ALL</constant> consider using a larger value to cover all bit
+       fields from now and well into the future, a numeric value like
+       <literal>2147483647</literal>.

       In PHP 3, the default setting is
