== Why is this an issue?
The ``++++`` element should provide the ``++lang++`` and/or ``++xml:lang++`` attribute in order to identify the default language of a document.
It enables assistive technologies, such as screen readers, to provide a comfortable reading experience by adapting the pronunciation and accent to the language. It also helps braille translation software, telling it to switch the control codes for accented characters for instance.
Other benefits of marking the language include assisting user agents in providing dictionary definitions or helping users benefit from translation tools.
Both the ``++lang++`` and the ``++xml:lang++`` attributes can take only one value.
