About elite skills

i am a monk/mesmer. Can i capture every elite skill for my character (i mean elite skills for both monk and mesmer) or there is a limited number of elite skills i can capture for my character?

Each class has about 15 elites (correct me if I'm wrong).
So yeah, if you kill a mesmer boss, you can use signet of capture and cap a mesmer elite..
No limits.

Warrior-16 elites
Mesmer-14 elites
The rest have 15 but you were right Ray, each class has about 15.
If you want you can make one character and unlock all the skills, just by changing secondary profesions after you ascend. My monk has 3 sets of elites(Mesmer,Monk,Necro) I believe, missing about 1-2.
