: http://issues.apache.org/jira/browse/SOLR-49 (XSLTResponseWriter) : could be committed. It has no impact on existing code and can be : useful for simple setups, demos, etc.
On the subject of stablizing the external APIs, the one thing about your patch in it's current format that I rememebr not being fond of using XML node attributes to configure queryResponseWriters instead of refactoring the code used to get requestHandler configuration using nested XML as a NamedList (which can easily be converted to SolrParams). Other then that, i agree it would be a really handy thing to have in our first release. -Hoss
