I haven't found it either.

Now I have looked in old mails, probably I remembered
linearized PDF:

| F.2.6
| ... This page object must explicitly specify all required
| attributes, such as Resources and MediaBox; the attributes
| cannot be inherited from ancestor page tree nodes.
| ...
| F.2.9
| ... Note that all Resources attributes and other inheritable
| attributes of the page object must be pushed down and replicated
| in each of the leaf page objects (but they may contain indirect
| references to shared objects).

But I don't think that pdfTeX wants to generate linearized PDF,
thus "non-inheritence" is probably not an issue.

Yours sincerely
