Hi,
What does the double bar mean (as opposed to the single bar)? Example:

[<'background-color'> || <'background-image'> || <'background-repeat'>
|| <'background-attachment'> || <'background-position'>] | inherit

I couldn't find anything with a Google search.

My only guess is 
|| inclusive or 
| exclusive or
