75	75	Local variable is a type of variable that can be newly created and used for a certain need.
76	76
77	77	So as to create a local variable "newVar" with a value equals to "var number 1", we should write this piece of XSL code :

84	84	The call of this new variable in the scenario is similar to previous system variables:  **${newVar}.**
