• item filter in activities (edit, delete, checkin, permissions, etc)
• "IF activity"
• item filter in lookup (when you select item column from in the lookup)
• Action execution conditions

In the 2 first filters, where you are filtering items based on the item columns, you can use the following X-path functions:

strings 

            substring-before(s1,s2)

            substring-after(s1,s2)

            concat(s1,s2)

            contains(s1)

numbers         

            celling(s1)

            floor(s)

            round(s)
