title: Groups of C# Attributes
body: <p>Is there any way to build a group of attributes?</p>
  
  <p>Before:</p>
  
  <pre><code>[SuppressMessage("Microsoft.Design", "CA1061")]
  [SuppressMessage("Microsoft.Usage", "CA1812")]
  [SuppressMessage("Microsoft.Design", "CA1064")]
  public abstract void Foo();
  </code></pre>
  
  <p>What I want:</p>
  
  <pre><code>[SpecialStuff]
  public abstract void Foo();
  </code></pre>
  
  <p>Is this possible? Can I build an attribute that groups others?</p>
