As indicated in #515 change of order of properties in ErrorInfo schema is confusing and it was not intended in #506 included in r3.3
Issue #522 can be also quickly resolved with the needed correction.

• Fix Typo in Gherkin Device Errors Template #523
• Fix: networkAccessIdentifier uses a real domain name in its schema example #529
• Remove "Hashing passwords" section from Security Section #509
• event-subscription-template.yaml and some APIs have a link to deprecated API Design Guidelines from r2.3 #531
