Per
http://www.dokuwiki.org/namespace_templates I've tried to create a template for an entire namespace but it is not working.
I have namespace one:two:three.
I want anything under two and two:three to use a template I have created.
I put my _template.txt in the two directory and new pages in two get initialized with the template, but new pages in three do not.
I moved _template.txt to __template.txt and now neither new pages in two or two:three get the template?
If I move it back to a single leading underscore it works again for two.
Any ideas?
