Resolving IRIs for resource documents in SVG Tiny 1.2

This seems to imply that if I have a document that contains many resource
references with the same relative URI, I have to perform an HTTP transaction
for each one to see if any of them result in a redirect. Wouldn't it make a
lot more sense to use the pre-redirect URI as the dictionary key, so I can
avoid a lot of network transactions?
