Template Boxes

1. Multi-line actions and formatters

• info boxes
• content templates

1. {{tpl_name param... }}
2. %%(tpl param... ) content%%

• WackoWiki Markup^[link1]

To make this approach expandable to whatever you like we just should treat wiki-pages as data objects.
Then one can use as I have mentioned before or any other kind of a new tool to work with such objects.
We have already page_lang VARCHAR(5) in pages table - to set language, and formatting VARCHAR(20) that can be used to say that some pages are not ordinary wiki-pages but "data objects".
This requires some changes to catalog, revisions, history tracking tools etc. -- Elar9000^[link2]

2. How to write your own content templates.
