This is a case of the WRAPPER directive in action:
http://template-toolkit.org/docs/manual/Directives.html#section_WRAPPER

"The WRAPPER directive provides a way of simplifying this a little. It
encloses a block up to a matching END directive, which is first
processed to generate some output. This is then passed to the named
template file or BLOCK as the content variable."

If you run "grep -r base.tt2 Open-ILS/src/templates" you'll find tons of
files use base.tt2 as a generic container via the WRAPPER directive.

Hope this helps,
Dan
