[OAI-implementers] Set membership and <setSpec> elements in headers

[Simeon Warner]

Hi Ben,

If an item is in Collections:Col1 then the headers for record from that
item should include only that setSpec and not Collections. The spec says:

"The list of setSpec [elements] should include only the minimum number of
setSpec [elements] required to specify the set membership. Using the
previous example of a set hierarchy, the header for an item organized in
set institution:florida should not include setSpec institution since that
is implied by the setSpec institution:florida."
(first bullet of the last set of bullers in sec2.6 Sets,

Cheers,
Simeon
