Information sent by capella when validating .

Hello;
I would like to ask you about severity of informations sent by capella (warning,error…),most of them are Warnings i don’t know if that means i must solve them (warning) or i must solve just the information kind (error).
I inspire this idea from my little experience with Rhapsody IBM because even if i had lot of warning i could execute my model.
Best regards.
