Assigns a value to a variable in a specified scope
The set tag assigns a value to a variable in a specified scope. It is useful when you wish to assign a variable to a complex expression and then simply reference that variable each time rather than the complex expression. This is useful in both cases: when the complex expression takes time (performance improvement) or is hard to read (code readability improvement).
The scopes available are as follows :-<a:set name="personName" value="person.name"/> Hello, <a:property value="#personName"/>. How are you?
