I have nested tag
today is not interpreted
<p th:text="#{today}"> <span th:text="${today}">16 december 2021</span> </p>
With this line, that work but that don't get the same output
<p th:text="#{today}"> </p> <span th:text="${today}">16 december 2021</span>
<p>
[[#{today}]]
<span th:text="${today}">16 december 2021</span>
</p>
or
<p>
<span th:text="#{today}" />
<span th:text="${today}">16 december 2021</span>
</p>
Outer tags overwrite their contents, so just move the outer text in.
