Description

Olingo always serializes Singletons in the schema with "Name" and "EntityType" attributes when generating metadata through org.apache.olingo.server.core.serializer.xml.MetadataDocumentXmlSerializer.appendSingletons(...).
The above method seems to use XML_ENTITY_TYPE that has the value "EntityType").
This is be non-compliant to the spec, which specifies "Name" and "Type" as attributes for a Singleton.
