• validation of numeric instances;
• regular expressions and patterns;
• default values for missing keywords;
• validation of container instances;
• validation keywords sorted by instance types;
• multiplyOf;
• maximum and exclusiveMaximum (for numeric items);
• minimum and exclusiveMinimum (for numeric items);
• maxLength and minLength (for stringified items);
• maxItems and minItems (for arrays);
• maxProperties and minProperties (for dictionaries);
• uniqueItems;
• required;
• enum;

• allOf;
• anyOf;
• oneOf;
• not;
• definitions;
• additionalProperties, properties and patternProperties;

Bender may support all of them by default. If something cannot be added into framework for any reasons need to implement examples of its usage.
