property. You can have events without uid. As the comment above it says, it's useful \
only if you want to implement eventModified/eventRemoved (so that it can locate the \
events in the model), which in case of eg. holidays is not needed, cause they are not \
going to be modified/removed. So there's no need to make those plugins more complex \
