Examples of AttributeAppender

org.apache.wicket.behavior.AttributeAppender
AttributeModifier that appends the given value, rather than replace it. This is especially useful for adding CSS classes to markup elements, or adding JavaScript snippets to existing element handlers.
```
 <a href="#" wicket:id="foo" class="link" onmouseover="doSomething()"> 
```
can be modified with these AttributeAppenders:
```
 link.add(new AttributeAppender("class", Model.of("hot"))); link.add(new AttributeAppender("onmouseover", Model.of("foo();return false;")).setSeparator(";")); 
```
this will result in the following markup:
```
 <a href="#" wicket:id="foo" class="link hot" onmouseover="doSomething();foo();return false;"> 
```
