It is possible to tie the validation of a document to editor actions via the studio.validateBefore property defined in application.properties. This property is to configure Studio to prevent certain activity on content items when they still contain errors. More specifically, you can specify that either checking in content or approving (and thus publishing) content will be not allowed in the presence of content errors. Setting the value of the validateBefore property to "CHECKIN" entails the check of both Checkin and Approve actions. Currently, the only supported options are "CHECKIN" or "APPROVE". Leaving the property value empty means that no such checks are imposed, and editors are allowed to check in, approve and publish even when content errors are detected.
