Well, the subject line pretty much says it all.  I am looking to add some process start code to my workflow which can access the ListItem property of the EventDetails structure so I can then query my SharePoint 2010 list to obtain information about the current listitem.   I can read and write to datafields, but don't see how to access the ListItem.

XML Fields
  MyWFName
    EventDetails
      EventDetails

        ListItem <-- to retrieve the ListItem (the listitems ID)
