Provides the standard XML-based configuration facility for CSI.
This configuration provider can use configuration data from three different sources in various combinations:
System properties may be used to alter the default behavior when the class is instantiated, or the values may be modified programmatically. The system property "com.sybase.security.core.XmlConfiguration.XmlValidation" determines if the input XML configuration should be validated against the XML schema definition. It must either be unspecified or must be set to "true" or "false". If it is unspecified then the XML configuration file is not validated against the schema.
System property values may be embedded into any provider option values included in the configuration file. Properties are referenced using the format ${system.property.name}.
