As far as FreeMarker is concerned, yes, but it's always a question if
the framework your are using gives sufficiently low-level access to
FreeMarker... Anyway, if it does, since "term" is a top-level data,
you could use a custom TemplateHashModel implementation that does
this. (If are using a java.util.Map as the data-model root, you could
wrap it into your TemplateHashModel implementation just before passing
to the template.process call)
