Cuaxochtli

[Frances Karttunen]

In the various colonial and modern sources that I used for compiling 
ADN, I didn't find an attestation of the word that marked vowel length. 
  Apparently Andrews didn't find any either.  So to find out if it's xo: 
or xo, we need to see what might be found in other modern variants of 
Nahuatl that preserve some reflex of distinctive vowel length.

Does anyone have relevant data?
