Declaring NavigationPropertyBinding EntitySet in JSON schema does not produce desired $metadata.xml output

[marcinbelczewski]

Having declared:

"entityType" : [
{
    "name" : "ParentType",
    "navigationProperty": {
        "name": "Child",
        "type": "ChildType"
    }...
}

and then:

"entitySet": [
    {
        "navigationPropertyBinding": [
            {
                "path": "Child",
                "target": "Children"
            }
        ],
        "name": "Parents",
        "entityType": "ParentType"
    }....

the $metadata XML that gets created contains:

<NavigationProperty Name="Child" Type="ChildType"/> 

in EntityType section however, the following "NavigationPropertyBinding" information is missing but seems to be required in such situation according to OData specs.

<EntitySet Name="PArents" EntityType="ParentType">
       <NavigationPropertyBinding Path="Child" Target="Children">
        </NavigationPropertyBinding>
