Correct I have a list of NVP's. But that is what I need. The idea is to
have a list of name value pairs where the name is used to generate the
tag and the value is the value to save. Isn't that how a NVP gets
serialized to an xml archive?
I have also tried
list< boost::serialization::nvp<V> > sl;
...
ar & sl;
...
which I thought would work since the elements of the list are NVP's
It also gets caught in the trap.
