MSDB Table User Permissions

Just out of curiosity, could someone point me towards a listing of the user permissions for the MSDB table? I have looked through BOL and on the internet and cannot find a good listing. An example would be something like...
dts_admin: <dts_admin description>

Thanks in advance.

Unfortunately msdb is being used by a number of different SQL Server services (built on top of SQL Server Engine, but shipped as part of SQL Server itself), and each type of service documents their own set of roles and usage (i.e. http://msdn2.microsoft.com/en-us/library/ms141053.aspx can help you with dts* principals), but there is no centralized documentation.

My recommendation right now would be to use msdn to search for any out of the box principal you want to know more about, and typically you will find the documentation for all related principals as well.

I hope this information helps,
