3/// Represents a reusable SQL fragment node in py_sql, defined by a `<sql>` tag in XML or an equivalent in py_sql.
4/// It allows defining a piece of SQL that can be included elsewhere.
5///
6/// # Example
7///
8/// PySQL syntax (conceptual, as direct py_sql for `<sql>` might be less common than XML):
9/// ```py
10/// # define a reusable sql fragment
11/// sql id='columns':
12///   column1, column2
13/// ```
