From: Derrick Stolee <derrickstolee@xxxxxxxxxx> Bundle providers may want to distribute that data across multiple CDNs. This might require a change in the base URI, all the way to the domain name. If all bundles require an absolute URI in their 'uri' value, then every push to a CDN would require altering the table of contents to match the expected domain and exact location within it. Allow a bundle list to specify a relative URI for the bundles. This allows easier distribution of bundle data.
