 * and path filtering defined by excludePaths/includepaths comma-separated classpath-style regexes.
 * Default values are supplied as part of the .project buildCommand when the QVTd nature is added.

 * The identified files are passed to a separate MultiValidationJob for concurrent non-blocking validation.
