public class ControlledValidationXmlBeanDefinitionReader
CXF reads a series of Spring XML files as part of initialization.
The time it takes to parse them, especially if validating, builds up.
The XML files shipped in a release in the JARs are valid and invariant.
To speed things up, this class implements two levels of optimization.
When a CXF distribution is fully-packaged, each of the Spring XML
bus extension .xml files is accompanied by a FastInfoset '.fixml' file.
These read much more rapidly. When one of those is present, this classs
reads it instead of reading the XML text file.
Absent a .fixml file, this class uses WoodStox instead of Xerces (or
whatever the JDK is providing).
The Woodstox optimization also applies to user cxf.xml or cxf-servlet.xml files
if the user has disabled XML validation of Spring files with
the org.apache.cxf.spring.validation.mode system property.
Note that the fastInfoset optimization is only applied for the
methods here that start from a Resource. If this is called with an InputSource,
that optimization is not applied, since we can't reliably know the
location of the XML.
