Changing an <element-tag> to an "attribute"
As seen in the Basic Table example, the DBWSBuilder-generated eclipselink-dbws-schema.xsd file derives <element-tag> names from the Database table metadata:

It is possible to change an <element-tag> to an "attribute" with a o.e.p.tools.dbws.NamingConventionTransformer
In the eclipselink-dbwsutils.jar, there are built-in transformers that form a Chain-of-Responsibility
