Why do I get only 1 ItemAttachmentDeleting event when deleting more than 1 file in WSS 3.0

Question

I have this requirement, using WSS 3.0, that when an attachment is added or deleted from a list item, I need to send an email to the users. I'm not having a problem with the emails; it's understanding how the following events work. I'm using the following 4 events:

ItemAttachmentAdding, ItemAttachmentAdded, ItemAttachmentDeleting, ItemAttachmnetDeleted

If I add 2 attachments to an item, I get ItemAttachmentAdding and ItemAttachmentAdded fired for each attachment, which is what I expect. But when I delete 2 attachments, I get ItemAttachmentDeleting and ItemAttachmentDeleted fired only once total (for both files). I expect this to behave like the Adding/Added events; both events for each file deleted. And unlike the Adding/Added events, I don't have access to the name of the attachments that were deleted. Seems inconsistent.

Is this the correct behavior for these events? And is there a way to identify the names of the attachments that were deleted?

I've quickly checked on 2010 version - there's the SPItemEventProperties.BeforeUrl property (and corresponding SPItemEventProperties.AfterUrl property). On ItemAttachmentDeleting event SPItemEventProperties.BeforeUrl contains the url of the targeted attachment. I hope it works similar in 2007 version.

Unfortunately in the 2010 version ItemAttachmentDeleting event is being fired once for each attachment.
