Could someone with access to the official text of ISO 27729:2012 tell me 
whether an ISNI is a name identifier or an entity identifier? That is, 
if someone changes their name (adopts a pseudonym, changes their name by 
to marriage, transitions gender, etc), should they be assigned a new 
identifier?

If the answer is 'No' why is this called a 'name identifier'?

Ideally someone with access to the official text would update the 
article at 
https://en.wikipedia.org/wiki/International_Standard_Name_Identifier 
With a brief quote referenced to the standard with a page number.

[The context of this is ORCID, which is being touted as an entity 
identifier, while not being clear on whether it's a name or entity 
identifier.]
