A regular markup language defines a way to describe information in
a certain class of documents (eg HTML). XML lets you define your
own customized markup languages for many classes of document. It

metalanguage for markup languages.";

For the stable distribution (wheezy), this problem has been fixed in

For the testing (jessie) and unstable (sid) distributions, this
problem has been fixed in version 2.9.1+dfsg1-1.

We recommend that you upgrade your libxml2 packages.";
