Convert TEXT MARKDOWNPHPEXTRA to TEIXML

The TEXT file extension, associated with PHP Markdown Extra Documentation, refers to plain text files used to write and store documentation. These files are simple, human-readable, and can be easily converted to HTML using Markdown syntax. The TEXT extension is commonly used for README files, configuration files, and other documentation purposes. Markdown Extra enhances the basic Markdown syntax with additional features like tables, footnotes, and definition lists, making it a powerful tool for creating well-structured documentation.

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.
