The standard does not take into account that the author of the document 
might be different from the author of the __content__ in the document?

What's more relevant when you search a document? The person who created 
the document in a computer or the author of the content of the 
document? Most of times it's the latter. If I have a library of ebooks 
and search an author name, I want to find the real author of the books, 
not the publisher name or whoever created the ebook.

I see, in the documentation we should not recommend using PDF metadata 
in a way deviating from the standard. Even though the interpretation of 
Author is ambiguous, as Chris and Andrew said.
