missing support for validUntil attr in root-anchors.xml
We should implement missing attributes from https://tools.ietf.org/html/rfc7958#section-2.1.1
Options at the moment seem to be add:
- XML parsing library
- CMS parsing library
- another hacky regex
None of these options is nice.
In any case we have inherent problem with parsing date, because Lua os
library does not provide an easy way to parse full ISO date format. We can either:
- find full fledged Lua library to parse such string
- call
strptime
in C (maybe easiest?) - use a hack and hardcode UTC offset (and check that in regex)
