>
> We have a number of code snippets in jackrabbit-core and many JCR clients 
> that do something like the following:
> * get the prefix/URI for a given namespace URI/prefix without throwing an 
> exception if the namespace is not found (return null instead)
> * get a Map containing all current namespace prefix->URI mappings
> * get the prefixed name for a given URI + local name pair in a given session 
> (without a dependency to the SPI)
> * safely register a given namespace (don't throw if the namespace is already 
> registered, automatically select an unused prefix if needed, etc.)
> I'd like to introduce a NamespaceHelper class in jcr-commons to cover such 
> common code.
