Plugin documentation includes plenty of invalid HTML. However, we
don't maintain these files, so we are not in a position to fix them.
Better, therefore, to suppress these warnings so that we can notice
and fix other problems over which we do have control.
Eclipse validation warns about invalid HTML content in all
Maven-generated "target/site/dependency-convergence.html" files. The
warnings are legitimate: these HTML files are indeed invalid.
However, we don't maintain the tool that generates these files, so we
are not in a position to fix them. Better, therefore, to suppress
these warnings so that we can notice and fix other problems over which
we do have control.
