#25 Incorrect validation of xs:dateTime with pattern

[Alexey Kolyanov]

Having the following element and type definitions:

<xs:element minOccurs="1" maxOccurs="1" name="CreatedDateTime" type="ESMP_DateTime"/>

<xs:simpleType name="ESMP_DateTime">
    <xs:restriction base="xs:dateTime">
      <xs:pattern value="((([0-9]{4})[\-](0[13578]|1[02])[\-](0[1-9]|[12][0-9]|3[01])|([0-9]{4})[\-]((0[469])|(11))[\-](0[1-9]|[12][0-9]|30))T(([01][0-9]|2[0-3]):[0-5][0-9]:[0-5][0-9])Z)|(([13579][26][02468][048]|[13579][01345789](0)[48]|[13579][01345789][2468][048]|[02468][048][02468][048]|[02468][1235679](0)[48]|[02468][1235679][2468][048]|[0-9][0-9][13579][26])[\-](02)[\-](0[1-9]|1[0-9]|2[0-9])T(([01][0-9]|2[0-3]):[0-5][0-9]:[0-5][0-9])Z)|(([13579][26][02468][1235679]|[13579][01345789](0)[01235679]|[13579][01345789][2468][1235679]|[02468][048][02468][1235679]|[02468][1235679](0)[01235679]|[02468][1235679][2468][1235679]|[0-9][0-9][13579][01345789])[\-](02)[\-](0[1-9]|1[0-9]|2[0-8])T(([01][0-9]|2[0-3]):[0-5][0-9]:[0-5][0-9])Z)" />
    </xs:restriction>
  </xs:simpleType>

In XML we have this:

<createdDateTime>2021-10-06T08:57:09Z</createdDateTime>

And when I run parseString() I receive a warning:

Obviously 2021-10-06 08:57:09+00:00 came from internal datetime manipulations.
