title: How can I refer to a i18n entry in .json files ?
body: <p>I am currently developing a UI with SAP UI5 and would like to internationalize all text in there. </p>
  
  <p>This is part of my view in .xml format. Getting the text in the specific languages by using the placeholders in {} brackets works fine here.</p>
  
  <pre><code>&lt;headerToolbar&gt;
      &lt;Toolbar&gt;
          &lt;Title text="{i18n&gt;orderDetails}"/&gt;
      &lt;/Toolbar&gt;
  &lt;/headerToolbar&gt;
  &lt;columns&gt;
      &lt;Column&gt;
          &lt;Text text="{i18n&gt;statisticsSubject}"/&gt;
      &lt;/Column&gt;
      &lt;Column&gt;
          &lt;Text text="{i18n&gt;statisticsNumber}"/&gt;
      &lt;/Column&gt;
  &lt;/columns&gt;
  </code></pre>
  
  <p>I also got a Tile Container in the view, which is getting it's contents from a .json file.</p>
  
  <pre><code>&lt;TileContainer
      tiles="{/Tiles}"
      height="200pt"&gt;
      &lt;StandardTile
          icon="{icon}"
          type="{type}"
          number="{number}"
          numberUnit="{numberUnit}"
          title="{title}"
          info="{info}"
          infoState="{infoState}"/&gt;
  &lt;/TileContainer&gt;
  </code></pre>
  
  <p>This is the relevant part of the .json file:</p>
  
  <pre><code>  "Tiles":
    [
      {
        "title":"Anmelden",
        "icon":"sap-icon://inspect"
      },
      {
        "title":"Abmelden",
        "icon":"sap-icon://inspect-down"
      },
      {
        "title":"Liste",
        "icon":"sap-icon://activity-items"
      }
    ],
  </code></pre>
  
  <p>As the titles of the tiles are currently german only, I would also like to internationalize them by using i18n. When I change a title to a placeholder in {} brackets, I can just see the placeholder in the final UI-result but not the appropriate translation. Is there a possibility to use i18n in .json files or will I need to find a different solution for storing the data for the tiles?</p>
  
  <p>Thanks in advance!</p>
