What HTML template language uses <$ command $> and <$= value_to_insert $> ?

Question

I'm trying to determine what the original language is of a place that includes snippets like:

<div class="responselist">
    <$ for ( var i = 0; i < responses.length; i++) { $>
        <div class="response">
           <div class="response-body" id="response-<$=responses[i].ResponseID $>"><$= responses[i].Body $></div>
        </div>
    <$ } $>
</div>

It looks to me like Zimbra template files. Documentation is here: http://zimbra.imladris.sk/download/src/GNR-601/ZimbraWebClient/docs/ajax/template.txt

It also appears that something called XMDL uses this but I couldn't find any documentation confirming this.
