[sightly] How to add extra option to an expression

[Feike Visser]

Hi there,

I am working to implement [0], to add basically dateFormat option to a Sightly 
expression.

Like ${ value @ dateFormat=’dd/mm/yyyy’ }

Attached I have this implemented, but it is being invoked.

Am I forgetting something?

Thanks!
Feike
