title: App.config working with custom sections
body: <p>I seem to be having some trouble identifying exactly how to verbally express what I'm trying to learn how to interact with. This is problematic from a search standpoint. I have been trying a variety of queries to find something related to the topic at hand, but have yet to be successful.</p>
  
  <p>Part 1 of the question is: How do I address and/or describe this scenario?</p>
  
  <p>I have an App.config with custom sections. I don't mean custom sections as in the attributes are "custom", I mean the entire node and its children are custom as follows:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;Business.Department.Domain.DomainConfiguration&gt;
      &lt;DomainPath path="path/to/place/"/&gt;
      &lt;OtherNode type="THING"/&gt;
      &lt;StartOfAnotherCustomSection&gt;
          &lt;OtherCustomThingsHere&gt;
              &lt;CustomThing Id="1" otherAttrib="PertinentDetails"/&gt;
          &lt;/OtherCustomThingsHere&gt;
      &lt;/StartOfAnotherCustomSection&gt;
  &lt;/Business.Department.Domain.DomainConfiguration&gt;
  </code></pre>
  
  <p>Again, I'm looking for a way to address these "custom nodes", as consulting Google/SO by mentioning custom nodes in an App.config, it directs me to things like this:</p>
  
  <p>On the MSDN side of things, I found a few links, this being one of them:</p>
  
  <p><a href="https://msdn.microsoft.com/en-us/library/2tw134k3%28v=vs.140%29.aspx" rel="nofollow">How to: Create Custom Configuration Sections Using ConfigurationSection</a></p>
  
  <p>The problem is that this link and others like it are referring to the following:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;configSections&gt;
      &lt;sectionGroup name="pageAppearanceGroup"&gt;
          &lt;section 
            name="pageAppearance" 
            type="Samples.AspNet.PageAppearanceSection" 
            allowLocation="true" 
            allowDefinition="Everywhere"
          /&gt;
      &lt;/sectionGroup&gt;
      &lt;!-- Other &lt;section&gt; and &lt;sectionGroup&gt; elements. --&gt;
  &lt;/configSections&gt;
  </code></pre>
  
  <p>Part two (which may not be necessary to answer if identifying how to address my problem results in presenting me with a means of better finding material to self-study):</p>
  
  <p>Since these nodes are a little unconventional, I'm not entirely sure how to access/traverse these settings. If I was to need to access the <code>DomainPath</code> node for its <code>path</code> value, how would I do such a thing?</p>
