Honestly, I don't think there's an easy way. I just grepped through the JAX-WS spec and the JSR181 spec and neither spec mentions anything about it. When we move to JAX-WS 2.1, we might be able to add support for @XmlElement(required=true). Right now, we don't support any of the JAXB annotations on the SEI interface methods. Some of those are required to be supported in jaxws 2.1. XmlElement isn't one of those, but could potentially be added.
The only way to do it right now would be to create "wrapper" types and use the XmlElement annotation there and use the @RequestWrapper/@ResponseWrapper annotations to point to those types. That should then use those types to generate the schemas and thus the JAXB annotations should be honored.
