Adam Wojnakowski: Trace Financial Ltd.:

I found that some schemas that seemed invalid against the JSON schema specification 0.4 - 0.7.
 
I’ve summarized the encountered issues below. Just wanted to check if this is intended and if so, why? Else, we just wanted to let you know.
 
Most of the schemas have a misplaced “additionalProperties” keyword. 
 
“additionalProperties” placed as child of “properties”, for example: file UBL-UnqualifiedDataTypes-2.1.json, line 207
though not prohibited, the “additionalProperties” keyword for type “array” has no meaning. An example: file UBL-CreditNote-2.1.json, line 58
 
The “format” keyword with value “date-time” is used together with a “pattern” keyword, but the pattern does not match a valid “date-time” format.
 
According to JSON Schema specification the date-time should comply to ISO 8601 and consist of:                                full-date T full-time
But this will never match some of the patterns. For example: 
 
                File UBL-UnqualifiedDataTypes-2.1.json, at line 218, defines a property called “DateContent” and the “format” : ”date-time” keyword is used.
                The regex pattern at line 226:   ^-*[^T:-]+-[^T:]+$
will not allow the ISO 8601 date time, where the time part is required with ‘:’ separators.
