I have no idea about relaxNG I'm afraid.

It is possible to "cheat" the plugin system and have a plugin that does 
both input and output. However, there are very good reasons for not 
doing this, most importantly separation of concerns, a plugin should 
only do one job, input, or output. This makes it much easier to maintain 
and resuse code.

Looking at your examples of redundant code:

site: I don't see this as the case, your input plugin takes your new 
schema and creates our internal format, so only documents the new 
schema, there is no need to document what it is converted into internally.

grammar: why is this needed on the output side? The output plugin should 
only work with our internal format.

documentation: isn't this the same as site?
