I see the need for the feature, but I am skeptical concerning the
implementation.
This PR reflectively modifies the contents of a String. This is prone to
cause problems, for multiple reasons. Strings cache hash codes, and strings
themselves are interned and shared.
Is there no other way to pass a default namespace to the mapping?---
