LOL .. again ... now it parses deep array structures, but does not enter the content into a CDATA Area ... So far a & seems to be a impossible char forteh rest Server ..
it isnt for the JSON Server so i patched the thing a little bit ;) I guess the guys at Zend are a bit of brain only workers ..... could be that i missed reading some tutorial or so .. but works anyway.

silly, but the zend rest server does not serialize nested arrays ... so i came up with a little fix (for the .7.0 incubator):
