Functions MUST NOT be used at the service root. Function imports MUST NOT be used anywhere except at the service root, especially not in query options or path expressions. Children of the default entity container MAY be used without qualifiers in URLs. Children of any schema in the metadata document MAY be qualified with the alias defined by the Schema element that defines them. All Schema elements within a CSDL document MUST have different values for the Alias attribute. Aliases introduced via the Alias attribute of Schema elements are now document-global and can be used in other schemas of the same document without needing a Using element. Using elements MUST NOT introduce clashes with aliases defined by other Using elements of the same schema (we forgot to specify this) or with aliases defined by other Schema elements of the same document.
