For example, ImagePlugin could instantiate a
DynamicAttachmentProvider, then generate a thumbnail and dump it to
the DynamicAttachmentProvider, without it actually ending up in the
repository and polluting it.
Dynamic Attachments don't show in the RecentChanges or when listing
page attachments, but they are accessible via the /attach/ URL and are
subject to all ACL restrictions of the parent page, just like a
regular attachment would.
It is a generic (and fairly simple) way of allowing components to
create Wiki content on-the-fly. However, at the moment it's limited
to Attachments only - it could be any WikiPage. For example, you could
have dynamic templates (e.g. when creating new page content),
thumbnails or PDF generation done fairly easily with this mechanism.
It's been around 2.6, but I don't think anyone's using it much. I've
been meaning to but haven't had the chance yet.

Oh goody, then I don't have to worry about fixing any issues with
it :-D
(BTW, anybody want to take the job of turning DynamicAttachments into
something more generic?)

I'd like to congratulate Janne on his checkin of the JCR code. It,
and the
from-scratch Priha implementation that underpins it, are remarkable
achievements. Nice work!
Yes, there are bunches of tests that need fixing. But that's ok.
We'll fix
'em.
My own next batch of checkins will include a rewritten Edit.jsp and
attachment uploads, including (for the first time) multiple
attachments.
This is implemented using ActionBeans, and it means
AttachmentServlet's days
are numbered. :)
