  \brief Native CMPIArgs implementation.

  This is the native CMPIArgs implementation as used for remote
  providers. It reflects the well-defined interface of a regular
  CMPIArgs object, 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.
