Special handling of derived types in the dynamic expression edm:Record. Why?
----------------------------------------------------------------------------

                 Key: ODATA-513
                 URL: http://tools.oasis-open.org/issues/browse/ODATA-513
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData CSDL
    Affects Versions: V4.0_CS, V4.0_ERRATA01
            Reporter: Martin Zurmuehl
             Fix For: V4.0_CS, V4.0_ERRATA01


We have defined a special handling of derived types in dynamic expression edm:Record:

14.5.14 Expression edm:Record
The edm:Record expression enables a new entity type or complex type instance to be constructed.
A record expression contains zero or more edm:PropertyValue elements. For each single-valued property of the record construct's type that is neither nullable nor specifies a default value an edm:PropertyValue child element MUST be provided. For derived types this rule applies only to properties directly defined by the derived type. For collection-valued properties the absence of an edm:PropertyValue child element is equivalent to specifying a child element with an empty collection as its value.
 
For me this special  looks superfluous.
