    // A MaterialTag represents a material (a type of block or item).

    // Block materials may sometimes also contain property data,

    // "material" plaintext: always matches.
    // "block" plaintext: matches if the material is a block-type material.
    // "item" plaintext: matches if the material is an item-type material.
    // "material_flagged:<flag>": a Flag Matchable for MaterialTag flags.
    // "vanilla_tagged:<tag_name>": matches if the given vanilla tag applies to the material. Allows advanced matchers, for example: "vanilla_tagged:mineable*".
    // If none of the above are used, uses an advanced matcher for the material name, like "stick".
