Convert TXT MARKDOWNMMD to TEIXML

The MultiMarkdown Documentation (MMD), stored with a TXT file extension, is designed for text documents formatted in MultiMarkdown syntax. The MMD format streamlines the conversion of plain text into various formats such as HTML, PDF, and LaTeX, essential for professional documentation. Introduced in 2005 by Fletcher T. Penney, MMD enhances traditional Markdown by supporting additional features like tables, footnotes, and citations, optimizing documents for better readability and usability in diverse technical environments.

The TEIXML file extension refers to the Text Encoding Initiative XML (TEI XML), a standardized format for encoding texts in the humanities and social sciences. Developed in the 1980s, TEI XML facilitates the digital representation of texts, enabling detailed markup of structural, semantic, and presentational features. It is widely used for creating and sharing digital editions of texts, ensuring interoperability and preservation. TEI XML is an application of Extensible Markup Language (XML), that provides a flexible and robust framework for text encoding.
