Validating a field depending on another field

[Mauricio de Abreu Antunes]

Hello JSON Schema group,

I read the docs and tried a lot of stuff to accomplish the following:

My schema has two fields:

"regex": {

    "type": "boolean"

},

"path": {

    "type": "string"

},

I would like to do something like:

WHEN regex field is "true" it should use JSON Schema "format" validator with "regex" value ("format": "regex").

WHEN regex field is False path will not be format: regex but "string".

I tried to use oneOf but most of the docs represent it validating one field only.
