I have given external tensor product its own entry.

What I would really like to do for the moment is record there sufficient conditions under which the fiber over $X_1 \times X_2$ is generated from external tensor products. I have added two references that discuss this for quasicoherent sheaves, but otherwise there is no discussion yet. Am being interrupted now.

(What I really want eventually is conditions such that $Mod(X_1 \times X_2) \simeq Mod(X_1) \otimes_{Mod(\ast)}Mod(X_2)$)
