title: how to translate placeholder text that is dynamically determined with a pipe using i18n tools
body: <p>I am in the process of using i18n to add translation to my project but I have a problem with trying to apply this technique to an input box with a placeholder that is dynamically determined by a pipe:</p>
  
  <pre><code>&lt;input
    i18n-placeholder="@@testPlaceholder"
    placeholder={{'text to be transformed here by pipe'} | PipeFormatter}}
  /&gt;
  </code></pre>
  
  <p>where PipeFormatter is a custom pipe i have created to transform the text based on requirements.</p>
  
  <p>How would I be able to provide the translation for the placeholder in this instance?</p>
