Good afternoon, I hope I understand you correctly. Yes, you can use the attribute name in NX in your language and use it in the mapping. From the Teamcenter side, you will need to specify the real name of the attribute, as in BMIDE:
"Local lang attr name" : ItemRevision.item_id /master=iman /description="Local lang attr desc"
if you mean about attributes in nx file then answer is yes, you can.
please, look at ArthurRM answer, keep in mind, that you should only "internal" name for Teamcenter attributes.
