Office Deployment Tool Config for 2013 Pro Plus

Hi!

   I'm trying to update an installation of Microsoft Office Professional Plus 2013 and wonder if somebody could help me with the correct Product ID to use for the Office Deployment Tool configuration.xml file?  Almost all the examples seem to use O365ProPlusRetail.

   The configuration documentation here discusses only Office 365: http://technet.microsoft.com/en-us/library/jj219426%28v=office.15%29.aspx

   But it links to this page, which lists product IDs, but no description (thank you not very much!): http://support.microsoft.com/kb/2842297/en-us

   There's a "ProfessionalRetail" there; elsewhere I've seen a "ProPlusRetail" which isn't listed there, and I'm hoping that if I get the right Product ID I can get this cantankerous update process to work!

   Thanks much,
       Rob
