[Axis2] What are the possible elements on services.xml ? We can use them to adjust Axis2's behaviors

[浮生半世情]

Dears
       There are three files named axis2.xml, services.xml and module.xml
on Axis2 package. Then, we can use them to adjust Axis2's behaviors. But,
who know all possible elements for them or where I can find any reference
documentations. For example, the following is my settings for services.xml.
I can use the tag named "elementFormDefaultQualified" to disable the
qualified characteristic. However, I want to know all possible parameters.
       Therefore, who can give me the assistances ? Thanks.
