perl-XML-Twig: The option to expand_external_ents, documented as controlling external entity expansion in XML::Twig does not work. External entities are always expanded, regardless of the options setting.

Weakness

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
