问题
Is there a way to list all documents in a view control (or a repeat control) and have a download button / link that will allow the user to download multiple attachments that reside in a rich text field?
I have found options using the @AttachmentName, however this lists all attachments on the document and does not restrict the attachments to just one the RTF.
I have a work around using a dialog box, which does work well, just not as clean as the option I was looking for.

In a view you can have a computed column. Any code you place into a dialog could be placed into a computed column. The getDocument() method of the XSPviewEntry gives you access to the document (recycle wisely).
update
To use a download control, use a repeat with the view as datasource and a panel per row. The panel has the data source pointing to a document. Use tr as tag for the panel.
This is only needed if you have attachments in other fields you don't want to show
