Generating the XSL File from CVA File

Hallo,

I’m quite new to UBL-World, therefore a „simple“ question:

How do I create /generate the XSL File from a CVA File?

 

The standard UBL 2.1 installation comes with the cva/UBL-DefaultDTQ-2.1.cva, who defines the rules fort he second phase validation. 

The val/UBL-DefaultDTQ-2.1.xsl is allready „compiled“ from the  CVA file, like I could read in the UBL 21 documentation. How is this file been generated? Is there an automatismus/script or some „code generator“? or do I have to write it for myself? One document only says that the XSL file has been generated using public available tools. 

 

Best regards,

daniel
