----------------------------------------------------------------
The XML APIs in Java are so great to have those pluggable transformations, so
let's use those. I wrote many frameworks doing this (in library world where I
am coming from, everything is XML, so you have partially really long chains of
handlers feeding some DOM trees / other representations) from one handler to
the other (I also managed to use XSL to convert XML to JSON to provide
schema.org from our library XML OAI metadata). So adding some abstract
"transform" hook into Solr core makes pluggable transformations easy.
So in general I would revert the whole stuff, make the transformation in core a
protected method and in contrib implement one "example" implementation of XML
transformations - using XSLT.

> The XSLT functionality, present in both XML /update loading, and also in the
> response writer, ought to move to the "scripting" contrib module because XSLT
> is a type of scripting. XSLT is risky from a security standpoint, and so
> should not be in solr-core.
