Hi folks,

The "IncludedCACertificateReportPEMCSV" 
<https://ccadb-public.secure.force.com/mozilla/IncludedCACertificateReportPEMCSV>
 report 
available from CCADB contains a column labelled "Mozilla Applied 
Constraints".

Presently the only row with a value in that column is the CA certificate 
with common name "TUBITAK Kamu SM SSL Kok Sertifikasi - Surum 1" 
(fingerprint: 
46EDC3689046D53A453FB3104AB80DCAEC658B2660EA1629DD7E867990648716), which 
has the Mozilla Applied Constraints column value of "*.tr".

I'm interested in creating automation that can build a set of trust anchors 
from the CSV content that would include imposed name constraints, but would 
appreciate input on my assumptions about the format of this column:

* Is it fair to assume this field will only express a single value? If 
multiple values are possible, would they be a JSON encoded array or use 
some other delimiter?
* Is it fair to assume a value like "*.tr" is intended to convey an RFC 
5280 name constraint extension carrying a permitted subtree with a base 
dNSName GeneralName with the value ".tr", and that future updates would 
follow the same pattern (e.g. using a wildcard character)?
* If the above interpretation is correct, is there a potential that 
excluded subtrees would be expressed somehow in the future? Would that be a 
new column, or somehow encoded into the value of the existing column?

Thanks!
