Translating results due to J. Labute into group cohomological language, A. Schmidt proved that a finitely presented pro-p-group G is mild and hence of cohomological dimension cd G= 2 if H 1 (G, F p)= U⊕ V as F p-vector space and the cup-product H 1 (G, F p)⊗ H 1 (G, F p)→ H 2 (G, F p) maps U⊗ V surjectively onto H 2 (G, F p) and is identically zero on V⊗ V. This has led to important results in the study of p-extensions of number fields with restricted ramification, in particular in the case of tame ramification. In this paper, we extend Labute's theory of mild pro-p-groups with respect to weighted Zassenhaus filtrations and prove a generalization of the above result for higher Massey products which allows to construct mild pro-p-groups with defining relations of arbitrary degree. We apply these results to one-relator pro-p-groups and obtain some new evidence of an open question due to Serre.
