Are soul cores global modifiers on weapons?

Or do they only apply to attacks made with the weapon?

For instance If I have +15% chance to bleed soulcore in a mace and use a totem does the totem get the bleed chance? Or only if I attack with said mace? Or if I socket a +15% chance to bleed soulcore in something does that cause any physical spells I cast to also gain that bleed chance?
