This appears to use 'DML' in an Ab Initio ELE context, not SQL DML. In Ab Initio's metadata, DML (Data Manipulation Language) defines record formats including field names, types, and layouts. Expressions, Transform Functions, and Key Specifiers are separate metadata concepts defined in DDL or other specifications.
