[status-update] XML_Serializer

Hi, as there have been some discussions about XML_Serializer, here's what I've planned: 1. Remove the GLOBAL variable and replace it with object properties => No static method calls possible anymore 2. If a special options attribute is added, the types will be added to the tags (object, array, int, float) 3. I will build an XML_Unserializer, which allows you to unserialize data. If there's a type attribute it will restore the original data structure 4. classes will be able to supply tag names and XML representations (like Alan suggested) With these changes everybody should be happy :-) Stephan
