 * valid parsers and skips any validation steps. This is NOT a generic
 * serialization function for in-memory blocks. For most purposes, see the
 * following functions available in the `@wordpress/blocks` package:
 *
 * @see serializeBlock
 * @see serialize
 *
 * For more on the format of block nodes as returned by valid parsers:
 *
 * @see `@wordpress/block-serialization-default-parser` package
 * @see `@wordpress/block-serialization-spec-parser` package
 *
 * @param {WPRawBlock} rawBlock     A block node as returned by a valid parser.
 * @param {Options}    [options={}] Serialization options.
 *
 * @return {string} An HTML string representing a block.
