Text classes

This is a gap it would be nice to fill.
Since it is not a small effort to do right there'd be a design side as 
well as implementation so it can't be just 'slid in'.
And I don't think just moving internal APIs to public is the way to 
approach it.
There are no current plans to allocate Oracle resources to do that work.
But this is an open source project, so if someone on this list is 
willing to design & contribute it - and of course
fix the issues and long term maintain it - then that would be great.
