Windows Workflow 4 stores its persisted bookmarks inside of the [System.Activities.DurableInstancing].[InstancesTable] table in the column [BlockingBookmarks]
So I was having an issue in my OpenAccess Domain Model getting a list of items in order to run queries on (give me all bookmarks pending across instances for X user...for example)
So that led me to make this...it'll dump bookmarks into this format
[ID][BOOKMARKNAME][CREATED]
Such that each row denoted a pending bookmark, and the ID column is not unique (lets say there's 4 bookmarks for the same InstanceID, thats 4 rows)
