title: Binding ValidationRules in one line?
body: <p>I have several one-line binding already written and I'd like to keep it that way if possible and if it still is humanly readable.
  Is there any way to rewrite this</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;TextBox.Text&gt;
      &lt;Binding Path="SomePath" NotifyOnValidationError="True" &gt;
          &lt;Binding.ValidationRules&gt;
              &lt;local:ValidationRule1&gt;&lt;/local:ValidationRule1&gt;
          &lt;/Binding.ValidationRules&gt;
      &lt;/Binding&gt;
  &lt;/TextBox.Text&gt;
  </code></pre>
  
  <p>in one line?, like </p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;TextBox Text="{Binding Path=SomePath, [ValidationRule1...]}" /&gt;
  </code></pre>
