  \brief Native CMPISelectExp implementation.

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

  \author Frank Scheffler

  \todo THIS IS NOT FULLY IMPLEMENTED YET!!!
