External entities may not have DTDs. They also may not have
standalone='...'" attributes in their text declarations. In
both cases, the XML spec requires fatal errors to be reported;
unless, that is, you've got a non-validating processor which
isn't reading the external entity!
If you find an "XML" processor which supports the nesting that
you're trying, return it to the vendor for a full refund ... ;-)
