I took note from John Cowan that comments can be used Syd!
I'm ignoring certain values (simplicity).

So far I've generated

<element name='doc'>
<oneOrMore>
<element name='dateTime'>
  <data type='string'>
    <param
name='pattern'><!--
Year -->(\[Y(01|0001)?\][^\[]?)<!--
Month -->(\[M(1|01)?\]?[^\[]?)<!--
Day -->(\[D(1|01)?\])?<!--
Hour -->(T\[H[01]{0,2}\]:<!--
Minutes -->\[m(1|01)?\]:<!--
Seconds         -->\[s(1|01)?\]\.<!--
decimal seconds -->\[f(1|01|001)?\])?</param>
  </data>
</element>


with test data of

<doc>
<dateTime>[Y0001]-[M01]-[D]</dateTime>
<dateTime>[Y]@[M]@[D]</dateTime>
<dateTime>[Y0001]-[M01]-[D1]</dateTime>
<dateTime>[Y]-[M1]-[D1]</dateTime>
<dateTime>[Y]-[M]-[D]T[H]:[m1]:[s].[f]</dateTime>
<dateTime>[Y][M]-[D01]T[H01]:[m01]:[s01].[f001]</dateTime>
<dateTime>[Y][M]-[D01]T[H01]:[m01]:[s01].[f001]</dateTime>

<!-- Errors -->
<dateTime>[Y100][M][D]T[H]:[m]:[s].[f]</dateTime>
<dateTime>[Y][M100][D]T[H]:[m]:[s].[f]</dateTime>
<dateTime>[Y][M][D10]T[H]:[m]:[s].[f]</dateTime>
<dateTime>[Y][M][D10]T[H]:[m10]:[s].[f]</dateTime>
<dateTime>[Y]-[M]-[D01]T[H01]:[m01]:[s0001].[f001]</dateTime>

</doc>

and exclusions of

   YWw for 'Two thousand and ten'
    MNn   for December
    Dlo   for 31st
    DWo   for twentieth

Its for a graph X axis, using dates.
As you see, we only need the Y M D H m s parts
which makes it a little easier.

I thought someone may have done it already

Thanks though. Appreciated.
