Suppose we have a Tense node with the following features:
T _ _ |NOM | |+present | |+fin | |-V | |+EPP | |2nd person | |PL | - -
All these features are sublabels of T. These sublabels can trigger movement to a projection of T; in this example, the EPP-feature forces movement of the subject to spec,T, and the [-V]-feature forces movement of the verb to T. The features of heads that are adjoined to a head, are also sublabels of this head; so if V adjoins to T, V's features also become sublabels of T.
