binarySeconds only works for xs:dateTime elements, which means that the
resulting infoset will also have a day/month/year/hour/minute/second
parts. There's no way around that. Note that the dfdl:calendarPattern
does not describe the format of the infoset, but is used to describe the
format of input calendar textual data. The infoset will always be
YYYY-mm-dd hh:mm:ss.
If you wanted only the year, you would need to parse the field as a full
dateTime, and then use inputValueCalc to extract just the year. For example:
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element name="dateTime" type="xs:dateTime"
dfdl:lengthKind="explicit"
dfdl:lengthUnits="bytes"
dfdl:length="4"
dfdl:binaryCalendarRep="binarySeconds"
dfdl:binaryCalendarEpoch="1970-01-01T00:00:00" />
<xs:element name="year" type="xs:int"
dfdl:inputValueCalc="{ fn:year-from-dateTime(../dateTime) }" />
</xs:sequence>
</xs:complexType>
</xs:element>
