Description

A lot of CSS/JS frameworks look for attributes on html elements that include a hyphen to do their magic (JQuery Mobile, Bootstrap, etc).

For example, in my JQuery Mobile app, I'd like to be able to say:

<@s.form ... data-ajax="false">
</@s.form>

Unfortunately, this doesn't work because Freemarker doesn't allow hyphens in macro parameter names. I entered an enhancement request for this here: https://sourceforge.net/p/freemarker/bugs/395/

I'm not sure when or if that might be fixed, so perhaps a work around would be to allow explicit dynamic attributes through some kind of parameter convention.

<@s.form ... >
  <@s.param name="dyn:data-ajax" value="false"/>
</@s.form>
