SetRawXml, as the name clearly states will update the entire element. Therefore we need to include the element tags as well as the information Here is a sample on how to update a DictionarySectionHandler

Configuration myconfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(null);

ConfigurationSection section = myconfig.GetSection(sectionName);

string rawXML = String.Format("<{0}>", section.SectionInformation.Name);

foreach (KeyValuePair kv in dic)
{
    rawXML = rawXML + String.Format("", kv.Key, kv.Value);
}

rawXML = rawXML + String.Format("", section.SectionInformation.Name);
