[AGENT++] more v3 questions

[Don Radick]

Looking through the source for V3 help, I came upon this in usm_v3.h:

// only for compatibility do not use these values and functions:
// =============================================================

#define SecurityLevel_noAuthNoPriv    SNMP_SECURITY_LEVEL_NOAUTH_NOPRIV
#define SecurityLevel_authNoPriv      SNMP_SECURITY_LEVEL_AUTH_NOPRIV
#define SecurityLevel_authPriv        SNMP_SECURITY_LEVEL_AUTH_PRIV

It looks like I should use SecurityLevel_noAuthNoPriv and 
NOT use SNMP_SECURITY_LEVEL_NOAUTH_NOPRIV, since
SecurityLevel_noAuthNoPriv is documented in the Doxygen output.

Correct?
