Industry standards allow a Certificate Authority (CA) to issue an SSL/TLS certificate for a domain that only has CAA records containing no "issue"/"issuewild" property tags.

When a CA queries a domain's CAA RRs and finds records with no "issue" or "issuewild" property tags in them, a CA can interpret this as permission to issue the SSL/TLS certificate for that domain. See Ballot 219: Clarify handling of CAA Record Sets with no "issue"/"issuewild" property tag.
