/**
 * Schema for validating MITRE object versions (`x_mitre_version`).
 *
 * Validates version strings in 'major.minor' format where both components are integers
 * between 0 and 99. This follows semantic versioning principles but excludes the patch number.
 * The version is incremented by ATT&CK when object content is updated.
 *
 * Note: This property does not apply to relationship objects.
 *
 * @example
 * ```typescript
 * xMitreVersionSchema.parse("1.0"); // "1.0"
 * xMitreVersionSchema.parse("12.5"); // "12.5"
 * xMitreVersionSchema.parse("1.0.0"); // throws error - no patch version allowed
 * xMitreVersionSchema.parse("100.0"); // throws error - major > 99
 * ```

 * Validates semantic version strings in 'MAJOR.MINOR.PATCH' format. This field helps
 * consuming software determine if the data format is supported. If not present on an
 * object, the spec version is assumed to be 2.0.0.
 *
 * Refer to the ATT&CK CHANGELOG for all supported versions.
 *
 * @example
 * ```typescript
 * xMitreAttackSpecVersionSchema.parse("3.0.0"); // "3.0.0"
 * xMitreAttackSpecVersionSchema.parse("2.1.0"); // "2.1.0"
 * xMitreAttackSpecVersionSchema.parse("1.0"); // throws error - must include patch version
