- * Fix structure of nested lists to follow HTML guidelines and normalize content in predictable way.
- *
- * 1. Move nested lists to have sure that list items are the only children of lists.
- *
- *		before:                           after:
- *		OL                                OL
- *		|-> LI                            |-> LI
- *		|-> OL                                |-> OL
- *		    |-> LI                                |-> LI
- *
- * 2. Remove additional indentation which cannot be recreated in HTML structure.
