That's also an unsolved use case I have.

The 'default' template of 'FormBase' contains the slot 'extra_info'
which could be filled with some hidden input fields.

I defined a new template for my own EditForm.

But now I would like to use the existing template in formlib
'pageform.pt' and fill the slot but don't know how.

Is this a possible way and the right way ?

How can I use the existing template ?
  It must be useable with metal:use-macro somehow.
