Use this function to return XPaths referencing URLs containing additional entry metadata to process with optional function prefixes. The URLs are not treated as feeds themselves and are processed only to extract metadata/content for the current entry. Wherever possible, feed URLs should be used that contain sufficient data to avoid the need for this function.

Inputs: xml (XmlDocument), document (Document)
Outputs: xpaths (list:{string} or table:{string->string} or table:{string->list:{string}})
