Convert TXT COMMONMARKX to TEIXML

The TXT file extension, which represents CommonMark Markdown Language with Extensions is a standardized, plain-text formatting syntax designed to be converted to HTML. CommonMark aims to improve the readability and portability of text, and it is widely used in documentation, forums, and note-taking applications. Extensions enhance its functionality, such as adding support for annotations, form inputs, and other features.

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.
