We discuss the discrete Zk D-brane charges (twisted K-theory charges) in five-brane backgrounds from several different points of view. In particular, we interpret it as a result of a standard Higgs mechanism. We show that certain degrees of freedom (singletons) on the boundary of space can extend the corresponding Zk symmetry to U(1). Related ideas clarify the role of AdS singletons in the AdS/CFT correspondence.
