title: InvalidSelectorException when trying to find elements by xlink:href attribute
body: <p>I'm trying to find elements like this:</p>
  
  <pre><code>&lt;use xlink:href="site.org/path/action#edit"&gt;&lt;/use&gt;
  </code></pre>
  
  <p>by a given attribute using this selector:</p>
  
  <pre><code>  public static By ElementsSelector { get; set; } = By.CssSelector(@"use[xlink:href='site.org/path/action#edit']");
  </code></pre>
  
  <p>and I find elements by:</p>
  
  <pre><code> Driver.FindElements(EditProfilePage.ElementsSelector)[0].Click();
  </code></pre>
  
  <p>but I get an exception:</p>
  
  <pre><code>OpenQA.Selenium.InvalidSelectorException: 'invalid selector: An invalid or illegal selector was specified
    (Session info: chrome=78.0.3904.87)'
  </code></pre>
  
  <p><strong>Question:</strong> How can I find elements with a given <code>xlink:href</code> attribute?</p>
