that 121 documents out of 895 failed to open in MSO Power Point 2010
after a roundtrip in LibreOffice. List of documents:
https://bugs.documentfoundation.org/attachment.cgi?id=129789. So I
validated some of those documents with Open XML SDK 2.5 tool and it
turned out most of them are affected by the same errors ( down to 6
right now ) which I've already reported in
https://bugs.documentfoundation.org/show_bug.cgi?id=104787. Some
documents are just affected by one and others by more than 1.

In my experiences (mainly with DOCX) Open XML SDK validation often
shows errors which are not problems for MSO while opening (I guess
there are some robustness in the import code), and also there are
some cases when SDK validation does not show a problem in the
document which makes MSO to fail opening it. So I'm not sure these
numbers you've got using this SDK correlate with the real number of
bugs we have here.

Then again, Xisco says he also tested against MSO 2010, so that's
probably the set of documents to focus on.

I meant not the document numbers, but the numbers of errors they are affected by:
"most of them [tested documents] are affected by the same errors ( down to 6  right now )"

Best Regards,
Tamás
