Use CVE-2014-5260.

This actually doesn't seem to be fixed. However, we don't immediately
see a security problem in version 0.65 (only a usability problem), so
a second CVE ID isn't assigned at this point.

Specifically, the latest version has:

  https://metacpan.org/source/AMBS/XML-DT-0.65/mkxmltype

  system("head -$lines $fname | xmllint --recover - > $fname");

which looks unintended (maybe $fname will always end up as a
zero-length file?). 

This apparently also affects libxml-dt-perl (0.65-1) from the
https://packages.debian.org/sid/libxml-dt-perl page.
