Core Features

• Types - Support for all YAML types: strings, numbers, integers, booleans, nulls, arrays, and objects
• Validation - Validation constraints including enums, constants, length, range, and pattern matching
• Composition - Schema composition with allOf, anyOf, oneOf, and not

Type System

YAML Schema supports the following types:

• string - Text values
• number - Numeric values (integers and floats)

Each type can be combined with validation constraints to create precise schemas for your YAML documents.
