Attributes: why would you need some localizable or scopable ones?

A localizable attribute can have a different value depending on its locale (combination of a language and a country). This option can be very useful when it comes to translating marketing information for a catalog of products or if you have a different value depending on a country (for example a price).

A scopable attribute can have a different value depending on the channel. It can be convenient if you want a different description on 2 channels or if the release date on each channel is different.

These options are easily configurable at the creation on the attribute.
