Wiki text rule for quote blocks. For example:
|
|
|
|
```
|
|
<<<.optionalClass(es) optional cited from
|
|
a quote
|
|
<<<
|
|
|
|
<<<.optionalClass(es)
|
|
a quote
|
|
<<< optional cited from
|
|
```
|
|
|
|
Quotes can be quoted by putting more <s
|
|
|
|
```
|
|
<<<
|
|
Quote Level 1
|
|
|
|
<<<<
|
|
QuoteLevel 2
|
|
<<<<
|
|
|
|
<<<

```
