Hello Klemens,

I have some XML experience and this looks well-formed to me except for the
syntax for CDATA is <![CDATA[<h1>this is the question</h1>]]>
(you missed a left square bracket)

Personally, I favor shorter element and attribute names (since XML data is
often sent over long distances ... the less bloat the better)

I particularly agree with your converting the numeric data to attributes and
protecting the question and answers in CDATA[]

for a quick tutorial/reference on CDATA, see http://www.w3schools.com/xml/xml_cdata.asp
