title: Wordpress Custom Type permalink containing Taxonomy slug
body: <p>I'm trying to create a permalink pattern for a Custom Type, that includes one of its taxonomies. The taxonomy name is known from the start (so I'm not trying to add or mix all of its taxonomies, just a specific one), but the value will by dynamic, of course.</p>
  
  <p>Normally, the Custom Type permalink is built using the <code>rewrite</code> arg with the <code>slug</code> param, but I don't see how I could add a dynamic variable in there.</p>

  <p>I'm guessing a custom solution is required, but I'm not sure what the best unintrusive approach would be.</p>
  
  <p>Is there a known practice for this or has anyone built something similar recently? I'm using WP 3.2.1 btw.</p>
