title: Use a variable for a namespace in an XSL transform
body: <p>This is probably a duplicate, but I haven't found the answer from any other posts so I will go ahead and ask.</p>
  
  <p>Inside an XSL file, I'd like to have variables that are the namespaces that will be output.</p>
  
  <p>Something like:</p>
  
  <pre><code>&lt;xsl:variable name="some_ns" select="'http://something.com/misc/blah/1.0'" /&gt;
  </code></pre>
  
  <p>Then in a template, do this:</p>
  
  <pre><code>&lt;SomeElement xmlns="$some_ns"&gt;
  </code></pre>
  
  <p>I have had no luck getting this work, even though it seems rather simple.</p>
  
  <p>Thanks for your time.</p>
