[Serusers] What are the possible HFNAME values in hf selects in ser rel_2_0_0?

Hi, What are the possible HFNAME values in hf selects in ser rel_2_0_0? When I try to add my own header and then use the a select for it the select is empty. I do it for P-Asserted-Identity header I did the following selects and no results: xlog("L_INFO", " route[AUTHENTICATION]: P-ASS: %(a)hf_value.p-asserted-identity \n"); xlog("L_INFO", " route[AUTHENTICATION]: P-ASS: %(a)hf_value.P_Asserted_Identity \n"); xlog("L_INFO", " route[AUTHENTICATION]: P-ASS: %(a)hf_value.p_asserted_identity \n"); xlog("L_INFO", " route[AUTHENTICATION]: P-ASS: %(a)hf_value2.p-asserted-identity \n"); xlog("L_INFO", " route[AUTHENTICATION]: P-ASS: %(a)hf_value2.P_Asserted_Identity \n"); xlog("L_INFO", " route[AUTHENTICATION]: P-ASS: %(a)hf_value2.p_asserted_identity \n"); Please point me what do I miss.
