Yup you are right .... however I am trying to run benchmarks with the two solutions.  

The xml solution will give us more flexibility in the future , just in case we do not have attribute/value lists :)

Come to think of it... You seem to be storing an attribute/value list in the database in XML. Is there any reason not to store the attributes and their values as a normal table? Your approach seems a bit over-complicated and you seem to have some trouble getting your own mind around it.
