Include hyperlink in text key

Hi everyone,

How do I properly include a hyperlink within a text key? Currently, I have it written in this format:

text.key = <a href="URL">Text</a>

But when I reference this in a component like this:

${text.format("text.key")}

...it displays exactly as written (showing the a href) rather than displaying hyperlinked text.

What am I doing wrong? 

Thanks!
