Needs some further cleanup before its ready to merge.
The main syntax forms, XML, JSON support read/write with a `Context` for
passing in configuration. Thrift does anyway.
TSV, CSV, Text work in this framework but have not been deeply integrated.
All old mechanisms to access features specific to a syntax should still
work.---
