Maps Attribute names to another name.
A common use is to construct legal Java identifiers, so that they can
be exposed in an MBean proxy with get/set routines.
For example "classpath-prefix" is not legal in a Java API; it could not
generate the methods getclasspath-prefix() and setclasspath-prefix().
Any legal mapping is OK. Suggested possible mappings include:
ClasspathPrefix, classpathPrefix, classpath_prefix, etc. These would
result in the method names: getClasspathPrefix(), getclasspathPrefix(),
getclasspath_prefix(), etc.
