This arrangement takes better advantage of the similarities between the now deleted widget renderer and the element renderer. It also obviates the need for wrapper elements around every widget.

Wiki text inline rule for wiki links. For example:
|
|
|
|
```
|
|
AWikiLink
|
|
AnotherLink
|
|
~SuppressedLink
|
|
```
|
|
|
|
Precede a camel case word with `~` to prevent it from being recognised as a link.
