XML stands for Extensible Markup Language, which is a specification developed by the World Wide Web Consortium (W3C). It is designed especially for web documents. XML enables the definition, transmission, validation, and interpretation of data between applications and organisations.
The major benefit of XML is that documents can be automatically generated by your system, which means there will be no need to key in the data. By having very little manual intervention XML will reduce your administrative burdens and allow you to submit your W1 Returns, W5, W6, W5D and W6D Warrants quickly and easily.
