A template may be executed directly or through [Template.ExecuteTemplate], which executes
an associated template identified by name. To invoke our example above, we
might write,

	}

or to invoke a particular template explicitly by name,

	profile := getFromLegend(legend, "Type: ", "unknown")
	data.Title = file + " " + profile
