Can a mark be maintained when the target is invisible?

Can a mark from a Fighter, Battlemind, etc. be maintained when the target goes invisible?

Remember, Invisible is not the same as Hidden. Even if someone turns Invisible, everybody on the battlefield still knows where s/he is unless he successfully becomes Hidden to them. – Snowbody Apr 26 '12 at 19:07
Yeap, appreciate that there is a battlefield awareness so the target is still known to be "there". – SteveC Apr 27 '12 at 10:21
