Thanks, Peter1. "I'm not looking whether one company is owned by another, so 
"is partof" does not matter.  I'm looking at the audit reports which, but 
thedefinition of ISAE 3000, list the "responsible party".  Myinterpretation is 
that "responsible party" is equivalent to "ownershipor control of the CA’s 
operations" in the Mozilla policy."ISAE International standard on assurance 
engagements - is a tool for auditors to produce one of two type of audit 
reports: a reasonable assurance engagement or a limited assurance engagement. 
The definition from ISA 3000 shows that "responsible party" and  "ownership or 
control of the CA's operations" in Mozilla policy are different concepts: 
Responsible  party―The  party(ies)  responsible  for  the  underlying  subject  
matter.  (Para.  A34) .Underlying  subject  matter―The  phenomenon  that  is  
measured  or  evaluated  by applying  criteria. 2. "As you call out, the CPS 
says "The legal entity responsible of TeliaCA is Finnish company “Telia Finland 
Oyj” (BusinessID 1475607-9)".Based on the audit report, Telia Finland Oyj is 
NOT the responsibleparty for the operations of the CA.  Prior messages stated 
that TeliaFinland is the legal owner. This indicates Telia Finland 
has"ownership or control of the CA’s certificate(s)".Again, there is no 
"responsible party" in Mozilla policy or underlying standards. According to RFC 
3647 the applicant under this root inclusion procedure has to disclose all of 
its PKI participants: CAs, RAs, subscribers, relying parties and other 
parties.3. "I frequently have not known which company my colleagues legally 
work for - it just doesn't matter for day to day purposes.", I fully understand 
you, but as we already discussed earlier, for CA’s personnel requirements see 
RFC 3647 section 4.5.3, anyone working for CA’s operations should contracted 
according to their roles in the CA's operations - also, let's not forget about 
the sanctions against personnel for authorised actions, unauthorized use of 
authority etc.4. "I'm suggesting improvements in Mozilla policy because this 
discussionhas shown the current policy does not provide clarity as to 
legalentities and because you have reasonably called out that havingclarity is 
beneficial to transparency."I do support your suggestion, however I’m not sure 
if this can be done within a specific root inclusion procedure - obviuosly this 
is something to decide for Mozilla.5. "I have zero experience with eIDAS, so I 
cannot comment oneIDAS-related practices.”If you don’t mind, I’ll give you more 
responding to Ryan’s comment, ok?Thanks,M.D.Sent from my Galaxy

see problems here, but at the same time proposing improvements to Mozilla 
policy - isn’t this "customization of rules" to the needs of a specific legal 
entity?I know from working for multiple companies that had operations 
indifferent countries and different tax jurisdictions that it is verycommon to 
have people employed by different legal entities who worktogether as a single 
team.  I frequently have not known which companymy colleagues legally work for 
- it just doesn't matter for day to daypurposes.  At one point I worked for XYZ 
Canada Ltd, my boss workedfor ABC GmbH, his boss worked for XYZ Inc in the US.  
The personworking for XYZ Inc was the senior vice president and general 
managerfor ABC and had responsibility and control of ABC, even if he didn'twork 
for ABC GmbH.  At another group of companies, we had people frommultiple legal 
entities working in the same building side by side.The fact that I worked for 
Example PQR LLC and my colleague worked forExample JKL LLC was only found if 
you looked at the details forentries in the corporate directory.  We both had 
email addressesending in @example.com.  This seems normal and common to me.I'm 
suggesting improvements in Mozilla policy because this discussionhas shown the 
current policy does not provide clarity as to legalentities and because you 
have reasonably called out that havingclarity is beneficial to transparency.  
This lack of claity is notunique to Telia; for example, the Globalsign CPS says 
"GlobalSignNV/SA and affiliated entities".  Given the lack of requirement 
ofpublic disclosure of the owner of the private key/certificate, I'm notsure 
how many other CAs in the Mozilla program have separation betweenthe operator 
and key owner.> While this is quite typical for Telia Company AB’s eIDAS 
related practices, I’m very concerned its happening here.I have zero experience 
with eIDAS, so I cannot comment oneIDAS-related practices.Thanks,Peter>>
