97ce4d9558 is described below
commit 97ce4d9558a6faa9224d91ddd899136248ccffb4

Refactor to support TCK tests adding custom transformations
The client filtering of extensions has a bug. Once that is fixed, some
TCK tests will fail because they expect they client to request a number
of TCK specific extensions. To support that, the TCK client needs to be
able to define those extensions. This refactoring will allow that to
happen. The bug will be fixed in a subsequent commit.
