Multiple Validation Keywords work in JSON Schema with the "AND" logic. The order of validation keywords is not important. In other words, all of them are applied individually to the JSON instance based their specified conditions.

For example, the following schema requires the JSON instance must a JSON String AND match the given regular expression pattern:

JSON Schema: 
{
    "pattern": ".*@.*",
    "type": "string",
	"minLength": 15
}

{"enum": ["YES", "NO"]}

Valid JSON instance:
