Licensing Situation

Hi,

I'm wondering about the license of the modules in this repository. The LICENSE file in the project root seems to be related to a BSD License, although it is not explicitly called that.

Some files in the repository are additonally licensed under Apache 2.0 license via source headers, e.g. [hyperjaxb/ejb/schemas/customizations/src/main/resources/config/maven-checks.xml](https://github.com/highsource/jaxb-tools/blob/5d21c2938660dcb0a608b0a6aa9084ba3c8f8f5d/hyperjaxb/ejb/schemas/customizations/src/main/resources/config/maven-checks.xml#L3) or [hyperjaxb/src/main/resources/config/maven-checks.xml](https://github.com/highsource/jaxb-tools/blob/5d21c2938660dcb0a608b0a6aa9084ba3c8f8f5d/hyperjaxb/src/main/resources/config/maven-checks.xml#L3)
