Create a new XML parser configuration with enhancements for the JAXP secure processing feature.

This new configuration supports the following properties that were defined for the JDK:

jdk.xml.entityExpansionLimit
jdk.xml.maxOccur
jdk.xml.totalEntitySizeLimit
jdk.xml.maxGeneralEntitySizeLimit
jdk.xml.maxParameterEntitySizeLimit

For now support will be limited to system properties and jaxp.properties.
