For the record: 1. The decision to allow presentation inside of <ci>...</ci> was deliberate. The view was that a "symbol" could have a very complicated appearance and still be treated as a single symbol for the purposes of content mathml. 2. For elipses in sums and sequences I have taken a more formal approach than has been suggested so far. I defined a function - roughly special_seq( base, operand , before_index_low, before_index_high, elipse_token , after_index_low, after_index_high ) so that special_seq( a , "+" , 1 , 3 , "..." , n-1 , n ) can be mapped to the presentation a_1 + a_2 + a_3 + ... + a_{n-1} + a_n and to the computational form Sum( a_i , i=1..n ); There is no ambiguity (at least no more than usual) for either the computation or presentation. Of course a transform is required.
