title: Reading attributes in ConfigurationSectionGroup
body: <p>Consider the following configuration group in a .NET .config file.</p>
  
  <pre><code>&lt;MySettingsGroup enabled="true"&gt;
   &lt;MySettingsSection enabled="true"&gt;
   &lt;/MySettingsSection&gt;
  &lt;/MySettingsGroup&gt;
  </code></pre>
  
  <p>The supporting classes are:</p>
  
  <pre><code>public class MySettingsConfigurationSection : ConfigurationSection
  {
      [ConfigurationProperty("enabled", DefaultValue = true, IsRequired = false)]
      public bool Enabled
      {
          get
          {
              // works fine
              return Convert.ToBoolean(this["enabled"]);
          }
      }
  
  public class MySettingsConfigurationGroup : ConfigurationSectionGroup
  {
      [ConfigurationProperty("enabled", DefaultValue = true, IsRequired = false)]
      public bool Enabled
      {
          get
          {
              // the way to retrieve attributes in sections is not supported by groups
              // return Convert.ToBoolean(this["enabled"]);
              return true;
          }
      }
  </code></pre>
  
  <p>How can the Enabled property on the MySettingsConfigurationGroup be implemented?</p>
