/*
FIXME: Use IDictionaryEnumerator.Entry instead and enumerate manually (faster and more robust).
It is faster because unboxing is avoided by going over
IDictionaryEnumerator.Entry rather than
IDictionaryEnumerator.Current. It is more robust because many
people may get the implementation of IDictionary.GetEnumerator
wrong, especially if they are implementing IDictionary<K, V> in
2.0. If they simply return the enumerator from the wrapped
dictionary then Current will return KeyValuePair<K, V> instead
of DictionaryEntry and therefore cause a casting exception.
using (IDictionaryEnumerator e = dictionary.GetEnumerator())

while (e.MoveNext())
{
writer.WriteMember(e.Entry.Key.ToString());
context.Export(e.Entry.Value, writer);
