The following example illustrates the currentDateTime extension function.
<Function name="DateTimeFunctions.currentDateTime" type="DATE">
<Extension library="com.sybase.ebd.eai.xsl.extensions" prefix="syexts"/>
<Argument name="date-format" type="STRING" minOccurs="1" maxOccurs="1"/>
</Function>
For each exposed Java method, you must have one Function element. For each Function element, you must have one Extension element to reference the Java package, and for each input parameter in the Java method, you must have one Argument element.
Use the following table to determine how the Function element and its children, the Extension and Argument elements and their attributes reference the Java class.
