Add headers

Thanks for working on this contribution! I think it is going along very nicely. This pull request will fix the build. Technically there are a few things that still need to be done:

  - Ensure that the TODO documentation is filled out
  - The xsd should be built using a spring-security-3.2.rnc document. You can find more info about rnc in the reference
  - Ensure trailing whitespace is removed. This can be done in Eclipse using the AnyEdit plugin. You can validate it got done by renaming .git/hooks/pre-commit.sample to .git/hooks/pre-commit and ensuring it is executable.

PS: You will probably want to squash this commit into your own to make it more concise and to get the correct commit format (i.e. JIRA id in the first part of the commit)
