We have searched for the decay BDs1+(2536)X and measured an upper limit for the inclusive branching fraction of B(BDs1+X)<0.96% at the 90% confidence level. This limit is small compared with the total expected BD(*)D(*)KX rate. Assuming factorization, the Ds1+ decay constant is constrained to be fDs1+<114 MeV at the 90% confidence level, at least 2.5 times smaller than that of Ds+.
