My StructuredTextViewerConfiguration extends
StructuredTextViewerConfigurationHTML. This seems to work (I am able to
provide my own content assist processors).
My OutlineConfiguration extends
org.eclipse.wst.html.ui.views.contentoutline.HTMLContentOutl ineConfiguration.
However none of the overridden methods is called (not even the
constructor), when I open a HTML file. The Outline View is there, but it
doesn't seem to use my class.
