I do not want to see how many bookmarks in OW 5 are updated. I have quite a large number of RSS feeds setup in OW 5 now, and that number on the Dock Icon can get pretty big. I also do not right-click the OW 5 Dock Icon to view the RSS feeds I have setup. I sent an email to the OW list and got the answer to my question from Brendan Sweeney. So thanks Brendan.
Now I think to turn the Dock Icon feature on and off, there should be a check box in the Bookmarks section of the OW 5 preferences, but alas all we can do is open up the Terminal and type (or paste):
defaults write com.omnigroup.OmniWeb5 ShowUpdatedBookmarksInDockIcon -bool false
