Frances Karttunen: 

TZOM(I)-TL fleece, bristles, mane / lana, seda, crin (S) [(1)Bf.7r]. TZOM(I)-TL is a variant of TZON-TLI. The form of the single attestation is ambiguous between TZOM(I)-TL and TZON-TLI. It is in the possessed construction ĪQUECHTETZON ‘his shawl, his neck protection.’ If there is semantic differentiation between TZOM(I)-TL and TZON-TLI ‘head of hair,’ then TZOM(I)-TL is slightly more appropriate. Otherwise, this does not constitute a genuine attestation of TZOM(I)-TL, as distinct from TZON-TLI.
