Epubcheck-1.1 errors reported by Lulu

PROBLEM:

I have sent this problem description to Lulu as well, as I am not sure whose 
problem it is!

I am trying to revise my book, which has been on sale with Lulu for a year. The 
problem is with their version of epubcheck-1.1, which appears to be a modified 
version of the real epubcheck.  It was apparently modified for Barnes & Noble.

1) It should really not be called epubcheck, as I believe the real epubcheck is 
up to version 3.0, and does not contain the tests that I ran into: 2 known 
(unmanifested files, and "invalid" publication date)), and some number unknown.

2) The Lulu epubcheck-1.1 was putting out two specific messages, which I have 
fixed, and now it just says "Did not pass epubcheck-1.1 validation", with no 
details. Is there a way to get details about what errors it is detecting?

3) My epub passes all the public validation programs with flying colours, 
including Sigil sweep and epubcheck-3.0, but keeps failing on the Lulu version. 
It also now passes the test for unmanifested files (there is a separate app on 
the Net for this).

4) Their message saying "invalid publication date XML" is misleading - my date 
was not incorrect, but apparently they wanted an opf:event entry for 
"publication" - they should have said something like "missing event indication 
on date"

5) I am only trying to revise my book because I felt that some of the tables 
were hard to read - there is no real change to the content, but I have now 
spent 2 days on this already! :-)

7) Looking at the Lulu forums, it is apparent that this problem is creating a 
lot of frustration on the part of the Lulu users - perhaps someone supporting 
epubcheck can clarify what is going on

OPERATING SYSTEM : Win 7 - 64-bit
Epubcheck - 1.1 (supposedly)
