XML, standing for Extensible Markup Language, is a widely-used system for defining data formats that both human and machines can read. This language, which is part of the 'Tech Skills' category, provides a standardized way for data interchange and is well-integrated across modern web technologies. It allows a systematical categorization or 'tagging' of data which helps in transmitting and organizing information, making it particularly beneficial in data storage, sharing, and transport processes.

Proficiency in XML is considered a valuable skill by numerous employers as it forms the building blocks of many web services and software programs. As an XML proficient, you would be expected to design viable, structured data formats and share data via both public and private networks. Further, you would be responsible for the interpretation and usage of data stored in XML format and ensure its smooth conversion to other formats when required.

A good foundation for developing skills related to XML often includes a firm understanding of HTML as it shares similar syntax rules. Additionally, a proficiency in any programming language (such as C#, Java, or Python) along with good problem-solving capabilities and logical thinking skills could be beneficial, as it supports XML parsing and provides a broader understanding of its utilization in real-world applications.

Knowledge of web protocols such as HTTP and SOAP, as well as related technologies such as XSLT (Extensible Stylesheet Language Transformations), XML Schema, and AJAX (Asynchronous JavaScript and XML), allows for fuller and more flexible utilization of XML. For those interested in data management, a background in SQL and an understanding of how XML can be employed in conjunction with databases could be particularly advantageous.

In a world where data interaction has become ubiquitous, XML offers a universal format for data interchange. Educational background in IT, Computer Science, or related areas would provide a strong ability to learn or master XML. This language's flexibility allows for a wide range of applications, providing a huge benefit for companies in fields ranging from web development to data analysis and beyond. Its technical implications make XML one of the highly sought-after skills in the tech industry today.
