Mark-like mechanics exist little, but reach, Combat Reflexes and Improved Trip seem to be good ways to "encourage" people to stay close to you. Disarm and Sunder can also help a lot - you really hate the guy that tries to take away your weapon(s) and will want to take him down first. Grapple might help, too, though I feel that's also a little "Bruteish" and maybe even "Lurkerish". (In 4E, there is a "Bugbear Strangler" with a special ability to grab a foe and use him as shield against attacks - I think that one is a Lurker.) Maybe it's a tool for multiple roles.
Grapple to pin down: Soldier
Grapple to use as shield: Lurker
Grapple to move foe: Controller
Grapple to swallow whole: Brute
Artillery and Skirmishers don't like to grapple. Artillery will hate it (hitting the wrong guy), Skirmishers might exploit other people being grappled (sneak attack), but certainly wouldn't want to pin themselves down like that.
For Brutes, a feat like Awesome Blow is nice.
To an earlier question, monsters with typically weak defenses are mostly Brutes and Artillery monsters.
