Identity Principal

Henry,

Excerpted from 
<https://dvcs.w3.org/hg/WebID/raw-file/tip/spec/index.html> :

[[
Identity_Interoperability
A Principal is a string that identifies an agent directly ( by reference 
) or indirectly ( via a property that relates the Principal to another 
identifier that directly identifies the agent. Well known Principals for 
an agent are the OpenId Principal, an Account Name Principal, a WebID, a 
public key, etc.... Usually each of these Principals come with different 
authentication protocols. This document should show how one can transfer 
trust gained via one authentication procedure to another Principal, by 
relying on relations published between these identifiers in a Linked 
Data space tied to a WebID.
]]

Question: Is an "Identity Principal" an Identifier or an entity denoted 
by an Identifier?

I believe the term "Principal" refers to an entity of type: foaf:Person 
[1].
