Symbolic tree transducers are programs by which to transform data trees with an infinite signature. In this paper, we show that the equivalence problem of symbolic top-down deterministic tree transducers (DTops) can be reduced to that of classical DTops. As a consequence the equivalence of two symbolic DTops can be decided in NExpTime, when assuming that all operations related to the processing of data values are in PTime. This results can be extended to symbolic DTops with lookahead and thus to symbolic bottom-up deterministic tree transducers.
