title: XSLT parameter is always empty <xsl:param name="mediaFolderId" select="/macro/mediaFolderId" />
body: <p>I created an xslt called GraphicsRowSlider with the following parameters</p>
  
  <pre><code>&lt;xsl:param name="mediaFolderId" select="/macro/mediaFolderId" /&gt;
  &lt;xsl:param name="title" select="/macro/title" /&gt;
  </code></pre>
  
  <p>And added the parameters title and mediaFolderId to the related macro.</p>
  
  <p>I then created new Macro Container data type and selected the macro GraphicsRowSlider as allowed macro. I then added a new field of the new data type into a document type and then imported that field into a template.</p>
  
  <p>Finally, from the content, I inserted the macro and added a title and selected media folder... However, I could see that the macro calls the correct xslt with the correct title and mediaFolderId but the parameters are always empty!</p>
  
  <p>Any thought?! Note, I always get this </p>
  
  <pre><code>&lt;?UMBRACO_MACRO macroalias="GraphicsRowSlider" title="Add Title here" mediaFolderId="1159" /&gt;
  </code></pre>
