Something that I think needs to be considered when moving forward with
gsearch is that the index may not always share a 1 to 1 relationship with
objects in fedora. In a very atomistic content model perhaps the solr
document is actually composed of parts from many related objects. These
types of decisions are currently very hard to make in XSLTs. While I think
XSLTs have a place in transforming metadata, there needs to be something
more.
