It turns out that this behavior is entirely correct. It depends on the XML
option. If you set the XML option to DOCUMENT, you can parse documents
including DOCTYPE declarations. If you set the XML option to CONTENT, then
what you can parse is defined by the production

XMLDecl? content

which does not allow for a DOCTYPE.

The default XML option is CONTENT, which explains the behavior.

Now, the supercorrect way to parse XML values would be using the XMLPARSE()
function, which requires you to specify the XML option inline. That way,
everything works.
