I would like an rss feed of a group's bookmarks from different points in time. Currently, I can only query up to 100 records with the "count=100" parameter. The api notes that you can use the "start=" parameter to call up records from different parts of the library, but that parameter doesn't work in my feed request:

question about what parameters can be used in RSS feeds
