Combining the two: binary files with custom fields

It is possible to specify both a <RawData> document, and fields such as <Title>, <Description>, etc. The binary document will be processed, and any other fields provided will override the values that came from the document.

This can be useful in situations where you have a Content Management System (CMS) that contains metadata about a document that doesn't actually occur anywhere in the document. You can do a custom dataload that pushes in the document, and the custom Title/Description/etc.
