Convert TXT MARKDOWN to XML DOCBOOK

Markdown Documentation files, often stored with a TXT extension, are utilized for writing plain-text formatted documents that are easy to read and convert to HTML. Originating in 2004 by John Gruber and Aaron Swartz, Markdown's intent was to create a simple syntax for writing web-based documents. It is widely adopted in software development, documentation, and content management systems due to its readability and ease of use. These files facilitate collaborative work and version control, making them indispensable in modern IT workflows.

DocBook XML, a subset of XML (Extensible Markup Language), serves as a markup language tailored for technical documentation. Developed in the early 90s, it was designed to standardize documentation across various software systems. Its uses include creating structured documents like books, articles, and manuals, ensuring consistency and ease of content transformation across different formats such as HTML, PDF, and EPUB. This standardization facilitates collaboration among developers and writers, enhances content reuse, and simplifies documentation maintenance.
