title: Style for wrapped text with spreadsheetml
body: <p>I generate my spreadsheet with xslt and want a cell with wrapped text (or better: a text with a line break in it).</p>
  
  <p>So my xslt generates the following XML for the sheetdata:</p>
  
  <pre><code>&lt;sheetData&gt;
    &lt;row r="1"&gt;
      &lt;c r="A1" t="inlineStr"&gt;
        &lt;is&gt;
          &lt;t&gt;
            a simple string
            line break jeeeehaaa
          &lt;/t&gt;
        &lt;/is&gt;
      &lt;/c&gt;
    &lt;/row&gt;
  &lt;/sheetData&gt;
  </code></pre>
  
  <p>After I'm finished building my Workbook, I open it in Excel; and there's no line break, just a simple one-line string in A1.</p>
  
  <p>has anyone a solution to this? Doesn't have to be in xml or xslt (but would be nice). I could also do some things in c#</p>
