When using the Native Format translation (in a file adapter) to convert a fixed-length format file to XML, if a field is defined in XSD as an integer, padded with zeros, and its value is zero, then the XML document will contain an empty element, rather than an element with a zero. This then fails schema validation.

The Native Format translator strips all padding from the input field, even when this results in an invalid value. In this specific case, a field is defined as:

<xsd:element name="UnidentifiedTransactions" type="xsd:nonNegativeInteger"
nxsd:style="fixedLength" nxsd:length="6" nxsd:padStyle="head" nxsd:paddedBy="0"/>

In the source file (input file), the field has the value "000000". Rather than setting the element in the resulting XML document to:


It is set to:


Which is not schema conforming, and thus fails validation. This is incorrect behavior for any numeric type. The XML schema validation error returned is: 

Invalid xml document.
According to the xml schemas, the xml document is invalid. The reason is:
Error::cvc-datatype-valid.1.2.1: '' is not a valid value for 'integer'.
Error::cvc-type.3.1.3: The value '' of element 'UnidentifiedTransactions' is not valid.
Please make sure that the xml document is valid against your schemas.
