Generating beans for wix.xsd with jaxb fails since

Question

I'm using JAXB (from Java 7) to generate beans for the schema definitions of WiX. But this generation fails since the wix.xsd (from the source tree of WiX 3.7) contains some regex with word boundary and other delimiters which are not allowed in a regex inside an xml schema definition.

Is there any way to proceed besides changing the schema definitions?
