Description

It would be nice if #createUrl() was protected, so that it can be used in derived classes.

In the specific instance where I need that: we're sending emails using Amazon Simple Email Service, which requires that attachments not just have a specific content type, but also an extension matching that content type.

To implement this requirement I've extended DataSourceUrlResolver, and return a URLDataSource that reports the original file name with the extension suitably enforced.
