It still feels a little awkward to me. I was just thinking of the  
introductory part of text books which explain the conventions used  
particularly regarding the positioning.

I assume "bounds" is also, ahem, out of bounds here? I've done some  
searching but can't find anything significantly better:

Can we use subscript and superscript of the symbol? I assume it isn't  
always sigma.
