 * Return flags for cms_error_action.  The model-specific implementation

 * flush). but it needs to return an indication to the caller as to
 * the high-level impact of the error.
 *

 * been cleared by the model-specific handling, and that no bad data
 * remains in the system as far as this error is concerned.
 *
 * CMS_ERRSCOPE_POISONED indicates that the uncorrected data has
 * been marked in some way to ensure that is cannot subsequently be mistaken
 * for good data.
 *
 * CMS_ERRSCOPE_CURCONTEXT_OK indicates that the interrupted context is
 * unaffected by the uncorrected error.
 *
 * CMS_ERRSCOPE_IGNORE_ERR indicates that the error should be ignored,
 * regardless of apparent current context status and presence of uncorrected
 * data.
 *
 * CMS_ERRSCOPE_FORCE_FATAL indicates that the error should be considered
