CSDL TimeOfDay literals inconsistent with XSD

CSDL XML 4.01 sectin 14.3.12 Time of Day

The edm:TimeOfDay expression evaluates to a primitive time value. A time-of-day expression MUST be assigned a value conforming to the rule timeOfDayValue in [OData‑ABNF].

ABNF shows:

timeOfDayValue = hour ":" minute [ ":" second [ "." fractionalSeconds ] ]

(so the second can be omitted)

But in http://docs.oasis-open.org/odata/odata/v4.0/os/schemas/edm.xsd

<xs:simpleType name="time">
<xs:restriction base="xs:time">
<xs:pattern value="([01][0-9]|2[0-3]):[0-5][0-9]:[0-5][0-9](\.[0-9]

)?"/>
</xs:restriction>
</xs:simpleType>

doesn't allow the seconds portion to be omitted, so is inconsistent with the ABNF timeOfDay references by CSDL spec.
