Multiple Schemas
A single content item may contain multiple schemas, such as:

WooCommerce
When WooCommerce is active, Product schema can use:
Product name
Description

Security
MarkupLoom validates custom JSON before storing it and re-encodes schema data with wp_json_encode() and JSON hexadecimal encoding flags before placing it inside a JSON-LD script element.
Administrator-only configuration is protected by WordPress capability and nonce checks.
Compatibility
WordPress 6.4 or later.
PHP 7.4 or later.
WooCommerce is optional.
