OData numeric literals have suffixes. e.g. 1008L and 10.99M
See: http://www.odata.org/documentation/odata-v2-documentation/overview/#6_Primitive_Data_Types
OData endpoints may contain Edm.Stream Element Types
See: http://services.odata.org/AdventureWorksV3/AdventureWorks.svc/
Note: this implementation will break queries, because the properties will not be parsed if media elements are present.

Conformance with 6.1.4 of the OData spec

See: http://www.odata.org/documentation/odata-v3-documentation/atom-format/#614_Stream_Properties_as_atomlink_Elements
There is some doubt as to the intent of the spec. See discussion here:
