Enum XmlTableColumn 

pub enum XmlTableColumn<X: Extension = NoExt> {
    ForOrdinality {
        name: Ident,
        meta: Meta,
    },
    Regular {
        name: Ident,
        data_type: Box<DataType<X>>,
        path: Option<Box<Expr<X>>>,
        default: Option<Box<Expr<X>>>,
        not_null: Option<bool>,
        meta: Meta,
    },
}

One column of an XmlTable COLUMNS specification (PostgreSQL’s RangeTableFuncCol).

The regular-column options (PATH/DEFAULT/NULL/NOT NULL) are order-free at parse — PostgreSQL normalizes them into fixed node fields — so they are stored positionally here and re-rendered in canonical order. PostgreSQL rejects a repeated PATH/DEFAULT and a conflicting/redundant NULL/NOT NULL at parse, which the parser reproduces.
