/// This class requires to store SoapAttrributes indexed by a key containg
/// both Type and Member Name. There are 3 approaches to this IMO.
/// 1. Make the key as "FullTypeName..MemberName", with ".." seperating Type and Member.
/// 2. Use a jagged 2D hashtable. The main hashtable is indexed by Type and each value
/// contains another hashtable which is indexed by member names. (Too many hashtables)
/// 3. Use a new class which emcompasses the Type and MemberName. An implementation is there
/// in TypeMember class in this namespace. (Too many instantiations of the class needed)
///
/// Method 1 is the most elegent, but I am not sure if the seperator is language insensitive.
/// What if someone writes a language which allows . in the member names.
