I only have my 3e PHB handy, but it seems to imply that half-elves are only produced in pairings where one of the indiviuals is an elf or both parents are some part elf.
AD&D is very specific on the issue:
"1)Anyone with both elven and human ancestors is eith a human or an elf (elves have only elven ancestors)
2)If there are more human ancestors than elven, the person is human; if ther are an equal number or more elves the person is half-even"
Ultimately this is a DM call, unless the language regarding this issue was changed in the 3.5 PHB (and I don't think it was in any significant way).
