How can I allow HTML links in translated strings?

Question

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 <a> then the error disappears.

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

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

Is it possible to translate those strings while keeping the links in the translation? How should I proceed?

Answer 1

the problem is the absence of the quotes. I try to insert this traslation on a drupal site and it work!

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

It also work with "

Have you tried split the string as below

$text = t('Some explanations here. You can find a more information 
<a href="@hhelp">on the help page</a>.', array('@hhelp' =>'../../help/mymodule',));

$text.= t('<br>Note: after changing this value, you may have to <a href="@hperformance">
clear the cache</a> for this setting 
to take effect.', array('@hperformance' => '../development/performance',));
