Localize Text Only

<!-- BAD -->
<!-- this will pull both the text AND the icon into the translation -->
<button i18n="action.some-text">
  some text
  <i class="fa fa-icon"></i>

<!-- GOOD -->
<!-- this will only localize the text -->
<!-- NOTE: ng-container does not create any new dom on the page -->
  <translate key="action.some-text">some text</ng-container>
  <i class="fa fa-icon"></i>

Updating Text

When updating text, update the identifier to match the new text field.

<!-- BAD -->
<!-- identifier does not match text after update -->
<label translate="">Address</label>

<!-- GOOD -->
<!-- identifier and text match -->
<label translate="label.address">Address</label>
