title: Regular expression and Obsolete attribute extraction in NDepend
body: <p>I've tried to search on the NDepend documentation if there is any possible way to do a regex on Obsolete Attributes? </p>
  
  <p>And is there a way to get the Obsolete attribute in NDepend at all? Any ideas or example of code on how to make a small Linq query to get an attribute of an obsolete?</p>
  
  <p>For example:</p>
  
  <p><code>//TODO! I WANT THE STRING USING NDepend!
  ObsoleteAttribute["Deprecated in 2007-01-23!"]
  </code></p>
