How can I allow HTML links in translated strings? I created a custom D8 module with all text strings declared in English, either via this->t(), t() or in various configuration (YML) files.

I am now in the process of translating those strings in French so that I can then extract them and package them with the module.

My issue: some strings for the interface contain HTML links (mostly refering to other Drupal admin pages); they display and work fine in English, but when I try to translate those strings via the Drupal UI, I get an error saying "The submitted string contains disallowed HTML". If I remove the &lt;a&gt; then the error disappears.

Here's an example of a string containing several links:

$this-&gt;t('&lt;p&gt;Some explanations here. You can find a more information 
  &lt;a href=@hhelp&gt;on the help page&lt;/a&gt;.&lt;br&gt;Note: after changing this value, 
  you may have to &lt;a href=@hperformance&gt;clear the cache&lt;/a&gt; for this setting 
  to take effect.&lt;/p&gt;', array(
  '@hhelp' =&gt; '../../help/mymodule',
  '@hperformance' =&gt; '../development/performance',
)),


Is it possible to translate those strings while keeping the links in the translation? How should I proceed?
the problem is the absence of the quotes. I try to insert this traslation on a drupal site and it work!  

&lt;p&gt;Some explanations here. You can find a more information 
 &lt;a href='@hhelp'&gt;on the help page&lt;/a&gt;.&lt;br&gt;Note: after changing this 
  value,you may have to &lt;a href='@hperformance'&gt;clear the cache&lt;/a&gt; 
  for this setting to take effect.&lt;/p&gt;
