If, for example, you passed in the name of the Confera in 
question as the form variable 'confera_name', you should
be able to do either:

 <!--#var "_.getattr(this(), confera_name)"-->

or simply:

 <!--#var "_[confera_name]"-->

...the main difference is that the second form will try to 
call the object automatically, which is in some cases not
what you want - either method should work for a Confera
though.
