Why XML language uses axl:version in the code?

- Axl:version is used to indicate that the XML document is an AXL document with the version mentioned on it.

- XML language is used to define the element and indicate the use of it using the axl:version.

- AXL processor processes the information that is used using the axl:version attribute and xsl:version.

- It provides the simplified process of using the stylesheets and use of the XSLT while writing the program.

- XSL also allows the use of XSLT so that media functions and MIME type can be used with the XML documents.
