Custom Similarity

[Grant Ingersoll]

I have a custom Similarity class that I would like to load.  It has a  
no-arg constructor, so it should work fine within Solr's context.   
However, it has the option for other constructor input values as well  
that I would like to be able to set.  Is there a way to set these  
values in Solr via the schema.xml declaration?  In looking at  
IndexSchema.java, it seems like it is not supported, but I was  
wondering if I was missing something.

In the past, I have used Digester/Beans to do these kinds of things.
I also have this issue for some Analyzers, but that is not as pressing  
at the moment.

Thanks,
Grant
