What is the latest schema for Chargeback api?

I have pulled the xsd from the cbm_api_ref_2.5.0

At the top of xsd I see:

<xs:schema xmlns="http://www.vmware.com/vcenter/chargeback/2.0" elementFormDefault="qualified" targetNamespace="http://www.vmware.com/vcenter/chargeback/2.0" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema">

BUT!

I am seeing that the xsd does not match up with the xml.

For example:

...

<EntityDetail>

    <Entity id="2098">

        <Name>NetworkUtilizationTest1</Name>

        <Type>111</Type>

        <Attributes>

            <Attribute id="1">

                <Name>vCloudEntityId</Name>

                <Value>VcloudVdcEntity-bf1280be-bf68-49bc-9d80-144f48fd5bb6</Value>

            </Attribute>

        </Attributes>

        <Parents> ...

The <Attributes> element is missing at schema.

<xs:complexType name="ReportEntityDetailType">

    <xs:sequence>

        <xs:element name="Name" type="NameType" />

        <xs:element name="Type" type="xs:int" />

        <xs:element name="Parents">

            <xs:complexType>

                <xs:sequence>

                    <xs:element name="Parent" maxOccurs="unbounded">
