It might be seen more like a code generator than like a tool for building computer languages. In fact, CodeWorker is a scripting language for generating code in a very flexible way. But first, it has to be feed with requirements specification, written in a Domain Specific Language (DSL) that you consider as adapted to your needs. The BNF is used to express the grammar of your DSL. If you just need a XML representation, don't worry about the DSL: CodeWorker already provides a XML parser in the script repository on the Web site. Normally, you don't use this BNF for describing a programming langage. But why not? I wrote a light C++ parser (light meaning that it doesn't manage macros), and I use it for checking source code (according to programming rules) or for generating UML class diagrams in PNG (I have built a DSL for describing class diagrams in a very declarative way). So, if you need a DSL, perhaps could you have a look to CodeWorker (<a href="http://www.codeworker.org)" rel="nofollow">http://www.codeworker.org)</a> rather than using XML + Xerces or something else.
