# Alt Syntax
+> Note: As from Struts 2.6 option to disable the AltSyntax has been removed and now using %{...} is the only way
+> to create an expression as stated below.

The _altSyntax_ is an option that can be defined in `struts.xml`. By default it is set to true and it is **strongly**
recommend you do not change that unless you are upgrading from WebWork 2.1.7 or previous versions.
