The content of the <<.wid let>> widget is the scope for the value assigned to the variable.
|!Attribute |!Description |
|//{attributes not starting with $}// |Each attribute name specifies a variable name. The attribute value is assigned to the variable |
|//{any attributes}// |Each attribute name specifies a variable name. The attribute value is assigned to the variable |
<<.from-version "5.2.3">> Previously, variable names were restricted to not start with a dollar sign. That restriction is no longer applied.
Attributes are evaluated in the order they are written. Attributes with the same name are allowed. Each time a duplicate attribute is encountered, it will replace the existing value set by the earlier duplicate.
