MetaYaml

Validates JSON, YAML, and XML data against a unified schema, with loaders for each format, enabling consistent validation across different file types as shown in the basic usage examples.

Supports diverse node types like text, number, array, prototype, and choice, with attributes for required, not_empty, and strict validation, allowing complex data structure definitions.

Automatically generates human-readable documentation from schema descriptions and provides experimental XSD generation for XML, useful for team reference or external validation contexts.

Includes loaders for common formats and allows writing custom loaders via the LoaderInterface, making it adaptable to additional data sources.
