Variable Expansion

Allows for the use of dynamic variables in the action.

Remark

Many actions support dynamic variable expansion in their attributes or content. Where supported, an embedded reference of the from $<variable-name>$ is replaced with the value of the local or global variable with the five name. $<variable-name>$ must be a legal variable name. For more information on what is a legal XML name, see W3C Extensible Markup Language.
