Correlations in rapidity space are presented for identified ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ and ${K}^{\ifmmode\pm\else\textpm\fi{}}$ in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation at 29-GeV c.m. energy. Short-range $\mathrm{KK}$ correlations indicate local flavor compensation in the hadronization process. Long-range $\mathrm{KK}$ and $\ensuremath{\pi}\ensuremath{\pi}$ correlations prove that the initial partons carry flavor. In addition, we observe significant $K\ensuremath{\pi}$ correlations as a result of heavy-quark decays.
