Request for additional dateTime datatypes

Hi,

In trying to derive a datatype for the W3CDTF
(http://www.w3.org/TR/NOTE-datetime), I came up with:

<xs:simpleType name="W3CDTF>
  <xs:union memberTypes="xs:gYear xs:gYearMonth xs:date xs:dateTime"/>
</xs:simpleType>

This will nearly do it except for the YYYY-MM-DDThh:mmTZD case (dateTime
with no seconds).

How about a xs:dateTimeNoSeconds datatype?  Or better yet a xs:W3CDTF
datatype?	

Another observation:  I don't have a specific need for these, but why aren't
there gHour, gMinute, gSecond, gHourMinute, or gMinuteSecond datatypes,
similar to the gYear, gMonth, etc. datatypes?  They could be used for events
that recur at a specific time each day, for example.

Thanks,
