You could disable the DTD and still use
valid syntax by putting this inside the marked section:
<![%sgml.features;[
<![%xml.features;[
<!-- ERROR: Exactly one of xml.features and sgml.features must be turned on! -->
<!ENTITY % dbpool.module "IGNORE">
<!ENTITY % dbhier.module "IGNORE">
]]>
]]>
They won't get very far without those two modules. 8^)
