/**
 * This class contains all properties of the Schema Namespace Information infoitem.  
 * These items correspond to the result of processing a schema document
 * and all its included/redefined schema documents.  It corresponds to the
 * schema component discussed in the schema specifications, but since it
 * is not like other components does not inherit from the XSObject interface.
 * This is *always* owned by the validator /parser object from which
 * it is obtained.  It is designed to be subclassed; subclasses will
 * specify under what conditions it may be relied upon to have meaningful contents.
