Attach:something/image.png means to use "image.png" that would be
attached to the page reached by [[something]].

So, since [[Test]] on pmwiki.org links to Test.Test, 
Attach:Test/clouds.jpg means to use the "clouds.jpg" file attached
to the Test.Test page.

However, since there's no XYZ.XYZ or XYZ.HomePage on pmwiki.org,
Attach:XYZ/image.png would refer to "image.png" attached to the XYZ
page in the current group (since [[XYZ]] refers to the XYZ page in the
current group).

Technically, attachments are never to groups, only to pages.  It's
possible to have a group of pages share attachments, but the attachments
are still considered to be attached to the pages and not the group itself.

Suppose I have a site organized with per-page attachments instead of
per-group attachments.  How should an author refer to an attachment
to page "XYZ" in the same group?  Well, if I were writing a link, I
would use [[XYZ]], so it makes sense that the attachment should be
Attach:XYZ/image.ext.  It *doesn't* make sense that I would have to
write the group name (i.e., Attach:Group/XYZ/image.ext) to access
an attachment of another page in the same group.

Also, Attach:Group/image.ext *does* work if the group has a start
page such as Group.Group or Group.HomePage (because in this instance
[[Group]] refers to a page in another group).
