Variable attribute values are indicated with double angle brackets around a [[macro invocation|Macro Calls]]. For example:

```
<div title=<<MyMacro "Brian">>>
...
</div>
```

The behaviour of variables invoked via widget attributes is not the same as when they are [[invoked via normal wikitext|Behaviour of variables invoked via normal wikitext]]. In addition, the behaviour depends on how the variable is declared:
