One more XML issue is found with the encoding/xml package: CDATA is omitted when we decode then encode the tokens.

For example,

<something>
  <![CDATA[
    anything
  ]]>
</something>

is output as

<something>
    anything
</something>

.

We probably should investigate some third party package that modifies the XML as little as possible to avoid more issues to appear in the future.
