Hi Russ,

For RFC 9709, you suggested "pkcs-9(9)” is correct (replacing "pkcs9(9)”) — 
does that apply to this document as well? 

Section 3:
      id-alg-hss-lms-hashsig OBJECT IDENTIFIER ::= { iso(1)
          member-body(2) us(840) rsadsi(113549) pkcs(1) pkcs9(9)
          smime(16) alg(3) 17 }

Appendix A:
   MTS-HashSig-2013
     { iso(1) member-body(2) us(840) rsadsi(113549) pkcs(1) pkcs9(9)
       id-smime(16) id-mod(0) id-mod-mts-hashsig-2013(64) }

… 

   id-alg-hss-lms-hashsig OBJECT IDENTIFIER ::= { iso(1)
       member-body(2) us(840) rsadsi(113549) pkcs(1) pkcs9(9)
       smime(16) alg(3) 17 }


Thanks,
RFC Editor/sg
