Hi I receive an exception while parsing a MetaData file with
EntityDescriptor as root.
Everything works fine if I used EntitiesDescriptor as root instead.
I thought that the EntityDescriptor could be a root Element. Am I
correct ?
(NOTE: I'm using a MetaDataFileProvider)

Exception:

This is the Meta Data I'm using :
