While you cannot map generated types to std::pair or std::map directly,
you can map them to types derived from these standard types. This will
make them pretty much eqivalent since you will be able to pass your
custom types where one of the standard types is expected. For example:

class LabelWeight: public std::std::pair<int, int>
{
  ...
};

The way to achieve this is to use the type customization mechanism
provided by C++/Tree. For more information on type customization
see the C++/Tree Mapping Customization Guide:

As well as the examples in the examples/cxx/tree/custom/ directory.
The one that is the closest to what you are trying to do is probably
'contacts'.
