  \brief Native CMPIString implementation.

  This is the native CMPIString implementation as used for remote
  providers. It reflects the well-defined interface of a regular
  CMPIString, 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 Once CMGetCharPtr() macro uses the appropriate function call instead
  of casting the internal hdl, store "CMPIString" type in there.
