Convert MARKDOWN to TEIXML

Markdown is a lightweight markup language with a plain text formatting syntax, primarily used in Markdown documentation files with the MD extension. Created by John Gruber and Aaron Swartz in 2004, it allows IT professionals to easily format text for web pages, readme files, and technical documentation. Markdown's simplicity and readability make it ideal for collaborative projects and version control systems. Its syntax is designed to be readable without compromising the document's formatting when rendered as HTML or other web formats.

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.
