title: Floating point numbers in XML
body: <p>what is the best way to handle floating point numbers in XML?
  If I have, for instance:</p>
  
  <pre><code>double a = 123.456;
  </code></pre>
  
  <p>and I would like to keep it as</p>
  
  <pre><code>&lt;A&gt; 123.456 &lt;/A&gt;
  </code></pre>
  
  <p>simply using 
  ...</p>
  
  <pre><code>myDoc.createTextNode(a.ToString());
  </code></pre>
  
  <p>is fine?
  Or should it be done with some Globalization stuff to make it region-independent?</p>
