FYI, Here's the link to the "XML Compilation" Thread started by Stefano.
http://marc.theaimsgroup.com/?t=97178196000002&w=2&r=1

Questions:
1. Shouldn't we be Caching the output of the Serializer and not the intermediate SAX events
themselves? (For example the SVG Serializer takes more time to process the request than the
Generator's or Transformers in the Chain)
2. Should we place the burden of deciding (whether the result of a request should come from the
Cache or generated again from scratch) on the Generator? (This was the case with C1 right?)

Thanks,
dims
