Schema validation not enforcing full datetime or timezone formats

Question

We have a schema definition which requires that all date elements are in the format YYYY-MM-DDTHH:MM:SSZ (eg 2010-06-05T05:26:59Z),
so to register this in Oracle we have added xdb:SQLType="TIMESTAMP WITH TIME ZONE" against the date elements.
However if a date contains a value in YYYY-MM-DD format, then the schema passes validation in Oracle. This is incorrect as the same
xml fails validation in Altova XMLSpy. [http://www.w3schools.com/schema/schema_dtypes_date.asp] confirms that all components of the date
format are required.
To illustrate my point:

The latter xml should fail. Validating this in XMLSpy it gives the error:
Value '2010-06-05' is not allowed for element <dateTime>.
     Hint: A valid value would be '2001-12-17T09:30:47Z'.
     Error location: Test / dateTime
     Details
          cvc-datatype-valid.1.2.1: For type definition 'xs:dateTime' the string '2010-06-05' does not match a literal in the lexical space of built-in type definition 'xs:dateTime'.
          cvc-simple-type.1: For type definition 'xs:dateTime' the string '2010-06-05' is not valid.
          cvc-type.3.1.3: The normalized value '2010-06-05' is not valid with respect to the type definition 'xs:dateTime'.
          cvc-elt.5.2.1: The element <dateTime> is not valid with respect to the actual type definition 'xs:dateTime'.
Is there any way to enforce validation of the full format?
