[ANN] Relax NG validation tool Serene 0.6 released

This is a one-time post to announce the Serene 0.6 release.

The purpose of the Serene project is to create an open source
validation engine implementing the JAXP 1.3 Validation Framework API
for RELAX NG that concentrates on good messages and a clear handling
of ambiguity and conflicts.

This release further improves message quality. The accent is on error
interpretation and reporting. Several bugs were fixed and a new
feature added.

Thank you,
