You can associate a type with an element using the
ITypedElement.getType() method. So, for example, you can decide for type
is "BLAH". Then getType should return blah and you shoudl associate your
merge viewer with BLAH as well (i.e. the type is usually a file
extension but doesn;t need to be).
To actually get the merge viewer to appear, you would want to make use
of a CompareEditorInput. In the prepareInput, you should prepare and
return your ICompareInput. The CompareEditorInput then takes care of
finding an appropriate viewer. You can host the editor input in an
editor by calling CompareUI#openInEditor.

After some thinking and stepping back from the problem to try and see the
big picture I got it working!
I was having problems trying to understand the actual link between providing
my functionality and where it hooks into the functionality provided by the
contentMergeViewers plugin!
But now I understand (for now anyway!)
Thanks for your great feedback.
Glenn.
