If you must use xml; then rather than passing around a dictionary, I'd use a class that represents that data, and use XmlSerializer to fetch it as xml:

[Serializable, XmlRoot("args")]
public class SomeArgs {
    [XmlElement("foo")] public string Foo { get; set; } 
    [XmlAttribute("bar")] public int Bar { get; set; }
}
...
SomeArgs args = new SomeArgs { Foo = "abc", Bar = 123 };
XmlSerializer ser = new XmlSerializer(typeof(SomeArgs));
StringWriter sw = new StringWriter();
ser.Serialize(sw, args);
string xml = sw.ToString();

This makes it much easier to manage which arguments apply to which queries, in an object-oriented way. It also means you don't have to do your own xml escaping...
