Must have when modifying InstallExecuteSequence in WiX

WiX allows developers to modify the install execute sequence, the basic idea is pretty cool as it allows developers to include all kinds of crazy custom actions. There is one downside, it's not well documented in the WiX schema documentation.

As it turns out, the after and before attributes that you can set here are actually actions from the table of standard actions of Windows Installer or actions from your table of custom actions.

The must-have resource for MSI development in general is : http://msdn2.microsoft.com/en-us/library/aa372845(VS.85).aspx and for more information about the standard actions available: http://msdn2.microsoft.com/en-us/library/aa372022(VS.85).aspx
