Comment(by vladan):

 The above definition also agrees with the one given in P.Soille,
 Morphological Image Analysis, Springer 2nd edition pg 65-68 (2002).

 It seems to me then, that Wikipedia, Serra and Soille all agree. The only
 thing is that erosion with flat structure elements (kernels) is more
 common, and consequently erosion with non-flat structure elements appears
 non-intuitive (as pointed out above by  warren.weckesser).
