title: thymeleaf disable message argument
body: <p>Is it possible to disable the arg {0} output when it is not available?
  Example:</p>
  
  <pre><code>messageSource.getMessage("my.message.property", new Object[]{12}, "fallback", LocaleContextHolder.getLocale());
  </code></pre>
  
  <p>this displays:</p>
  
  <pre><code>Child 12 Years old
  </code></pre>
  
  <p>now sometimes I don't have the age of the children, so my args would be:</p>
  
  <pre><code>messageSource.getMessage("my.message.property", null, "fallback", LocaleContextHolder.getLocale());
  </code></pre>
  
  <p>the display is now:</p>
  
  <pre><code>Child {0} Years old
  </code></pre>
  
  <p>Is it possible to disable the {0} on the output?</p>
