No "additional" parameter is used with generic templates. Regardless whether "hooks"
or generic templates are used, the data that is used to uniquely identify the node
(and the template that will match it) -- this data must be the value of some
variable or parameter.

In your examples you're using the $abc variable, and it serves the same purpose as
the template reference parameter, passed to a generic template.

Also, I'm using the assumption that the authors of the generic template and the
templates that use (call) it are completely different persons, most probably not
knowing anything about each other. Therefore, generic templates will come handy in
writing applications to be used as a base for the development of other applications
-- e.g standard template libraries.
