Clarify scope uniqueness for EntityContainer name
-------------------------------------------------

                 Key: ODATA-302
                 URL: http://tools.oasis-open.org/issues/browse/ODATA-302
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData CSDL
    Affects Versions: V4.0_WD01
            Reporter: Evan Ireland
            Priority: Minor


CSDL spec (2013-03-12) says:

12.1.1 The Name Attribute

The entity container MUST provide a unique SimpleIdentifier value for the Name attribute.

---

It isn't clear whether this uniquess is within the scope of the Schema, or the entire metadata document. For example, consider:

<edmx:Edmx xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx";
           Version="4.0">
  <edmx:DataServices DataServiceVersion="4.0" >
    <Schema xmlns="http://docs.oasis-open.org/odata/ns/edm"; Namespace="ODataDemo1">
      <EntityContainer Name="DemoService" IsDefaultEntityContainer="false">
      </EntityContainer>
    </Schema>
    <Schema xmlns="http://docs.oasis-open.org/odata/ns/edm"; Namespace="ODataDemo2">
      <EntityContainer Name="DemoService" IsDefaultEntityContainer="false">
      </EntityContainer>
    </Schema>
  </edmx:DataServices>
</edmx:Edmx>

Note how there are two DemoService containers, each is unique within the scope of its parent Schema. However DemoService is not unique within the metadata document.
