Attributes for each variation ?
I've seen here and in the faq (http://www.drupalcommerce.org/faq/product-attributes) but i'm not sure.
Is it possible to have some attributes for each variation? For example, I want to keep the weight for each variation of a same product.
In the same way, is it possible to have dependencies between the variations or sub-variations ? For example, can I say for the "blue" version of my product there is only the sizes "M","L".
thanks for helping.
