Randall Hauch commented on DNA-230:
-----------------------------------

Added a method to the NamespaceRegistry interface to obtain a snapshot of the namespaces (prefix and namespace URI) in the registry.  Also changed an BasicExecutionContextFactory to use this method.

> NamespaceRegistry has no ability to obtain a consistent snapshot of the prefix/URI pairs, which is important for a thread-safe and concurrent namespace registry.  Also, may want an alternative registry that takes a register behavior enum specifying what to do when registering a namespace if that namespace or prefix is already used.  Options include: 1) replace, 2) use automatically generated prefix, 3) fail
