Creating the Abstract Message Definition

This document assumes that you are working with an existing XML Schema Definition (XSD) or that you are creating an XSD. There are a number of tools available that help you create an XML schema, including NetBeans. Once you create an XSD you can apply the Custom Encoder as described in this document.

Recursive Structure

A recursive structure is allowed in an XML schema document used to define a custom structure. The recursive elements can be introduced inside a local XML schema definition by import statements, or by include statements, in the XSD.

The Custom Encoder supports both linear recursion and mutual recursion by import statements. It also supports mutual recursion from include statements.

Binary Data Types

The Custom Encoder supports elements of binary data type, as well as String data type. Far an element field of binary data type, the data type of “hexBinary” or “base64Binary” can be specified in the XML schema using the XSD editor.

Note that, base64 encoded data expands by a factor of 1.33 times the original size, and hexadecimal encoded data expands by a factor of 2 times original size, assuming an underlying UTF-8 text encoding in both cases. If the underlying text encoding is UTF-16, then these numbers double.
