/**
* There are cases where a WSDL definition is kept in memory
* in case it needs to be accessed during runtime. In situations where
* there are lots of WSDL definitions or big WSDLs, the memory footprint can be
* huge.
*
* This class provides support for processing a WSDL4J definition
* with a lower memory footprint. This is useful for certain
* environments.
*
* This class makes the decision on which implementation to use
* to reduce memory footprint. This allows other implementations
* to be used for specific environments without adding lots of extra
* overhead to every environment.
