Set Message Property

Hi, I want to create a plugin that intercepts a message and and a new property. Is this possible?

I looked at the smack library for clients and they can add properties http://www.igniterealtime.org/builds/smack/docs/latest/documentation/properties. html

using a plugin the same should be possible. Can someone tell me what I can use to modify

add properties to an **org.xmpp.packet.Packet **or org.xmpp.packet.Message after intercepting it?

Best Regards,
