DTDillä refers to a Finnish expression often used in informal contexts, particularly in online communication or casual conversation. It is a colloquialism that translates roughly to "by DTD" or "with DTD." The exact meaning and context can vary, but it generally implies a method or manner of doing something that is perceived as straightforward, efficient, or perhaps even a bit crude or basic, stemming from the technical concept of a Document Type Definition (DTD).
