XML Schema Definitions (XSD's) are usually complex -- closer to pseudocode than human-readable English.
The XSD will be used to generate the wsdl in later sections.
However, in most cases it is easier this way,that was defined above.
There is an optional property for 'request Suffix' and 'response Suffix'.
If you use XSLT 1.0 then you do not have that option, in that case you either need to provide a dummy XML input or you can choose one of the schema documents as the primary input document.
