Invalid JSON (Typo)

[watuwo]

A core specification example contains:

...
"pattern": "\d\d\d\d-\d\d-\d\d",
...

This is not JSON.

Can you provide a link to the section where this is found?

This is partial JSON. It's commonly understood from the ... that there is more to the JSON text above and below.

Do you have a suggestion on how to do this another way?

I think it needs to be "\\d\\d\\d\\d-\\d\\d-\\d\\d" in order to produce the regex \d\d\d\d-\d\d-\d\d

Yes, the backslashes were forgotten. That is what I meant.
