i18n - how to pass variable and html code in message

So I need to do something like:
Here is my message with inner_variable, ok.

inner_variable gonna be set in js and I need styles for it.

I tried something like:

.html

${'message' @ i18n, format='<span class="email-address__text"></span>'}

.xml

sling:message="Here is my message with {0}, ok."

But the span works like text and I can't set any values. Any suggestions?
