Clare, The <sep/> element only comes into play with explicit representation of numbers - inside of <cn> tags. It is not allowed inside of <ci> tags. While one might imagine a markup such as <ci type="complex-cartesian">x<sep/>y</ci> the association of x with a type would be implicit in the construct and the recommendation generally avoids inferring types from position. The cn tag use of <sep/> was a consession to the special needs of actual numeric data. Your best bet for a symbolic representation of complex-cartesian coordinates is something like <apply><csymbol definitionURL="complex-cartesian"/> <ci type="real">x</ci> <ci type="real">y</ci> </apply> It is especially helpful if the definitionURL point to some standard definition such as an entry in an OpenMath dictionary.
