  \brief Native CMPIEnumeration implementation.

  This is the native CMPIEnumeration implementation as used for remote
  providers. It reflects the well-defined interface of a regular
  CMPIEnumeration, however, it works independently from the management broker.
  
  It is part of a native broker implementation that simulates CMPI data
  types rather than interacting with the entities in a full-grown CIMOM.
