Coming back to this topic, I would also agree to changing the "CA" term 
with "TSP" which is more clearly referred to as an organization. This 
will also help to make a subordinate CA definition clearer because it is 
currently being used in the BRs as a non-affiliated organization AND as 
an Intermediate CA Certificate of the organization in control of the 
Root CA.

The following definitions would come from a "strict" interpretation of 
the terms "Certification Authority" and "Subordinate CA" of the current BRs.

*Intermediate CA Certificate:* A Certificate issued by a Root 
Certificate or another Intermediate CA Certificate which is deemed as 
capable of being used to issue new certificates and which contains an 
X.509v3 basicConstraints extension, with the cA boolean set to true. If 
an Intermediate CA Certificate is issued to a non-affiliated 
organization, then this Intermediate CA Certificate is also referred to 
as an Intermediate CA Certificate of a Subordinate CA.

*Subordinate CA:* A non-affiliated organization in direct or indirect 
control of an Intermediate CA Certificate capable of being used to issue 
new certificates for that organization.

Does this seem any clearer?
