Module for template {{Clade transclude}} with functions for partial transclusion of cladograms made with the {{Clade}} template.
Usage
{{#invoke:Clade|main}}
Parameters described at {{Clade transclude}}.
Testcases:
- {{Clade transclude/testcases}} (examples using nested subtrees)
- {{Clade transclude/testcases2}} (examples with all trees at basal clade)
