My suggestion is to add the "Cross Site Scripting" Signatures and keep only "Learn" and "Alarm" checked. So you have to unchecked the "Block" action.
Keep this configuration 2 weeks for example and after that verify from the "Event Logs" if you got to much incidents. In this case you can fine tune your policy.
N.B: If the VS is exposed on the internet be sure to identify the authorized traffic and not accept malicious traffic.
Hope it helps
Regards
