title: Variable Attribute Values
type: text/vnd.tiddlywiki
Variable attribute values are indicated with double angle brackets around a [[macro invocation|Macro Calls]]. For example:
```
>>
...
```
<<.warning "The text from the definition of the macro will be retrieved and text substitution will be performed (i.e. <<.param $param$>> and <<.param $(...)$>> syntax). The value of the attribute value will be the resulting text. Any wiki syntax in that text (including further macro calls and variable references) will be left as-is.">>
