hello, i'd like a clarification about <mo> operators that can be both largeop and stretchy according to the spec. it seems to me that the same operator having both largeop and stretchy specified is either conflicting or redundant. for example, <mo>⋁</mo> has by default both largeop and stretchy to be set. am i right in assuming that in displaystyle, a larger version of ⋁ is to be used no matter whether the stretchy attribute is explicitly set or not ? in that case, even in non-displaystyle are we supposed to use the normal size ignoring the stretchy attribute ? i am trying to figure out when should the stretchy attribute have any effect on the operator if largeop is not to be ignored in both display and textstyle. in TeX, operators that are "largeop"'s (eg. sum, prod, vee, ...) and operators that can stretch (eg. (,),[,],...) are separate groups and not mixed together. i am wondering if the authors of the mathml rec have found examples where it is useful to mix the two and if so how are these two attributes meant to interact with each other ? thanx - shyjanReceived on Tuesday, 8 August 2000 11:25:30 UTC
