My current view on EPUB conformance is that seems to be important to
have full conformance in some cases (as Daniel reported) and even if I
think that having such a level of conformance is pointless or even
wrong, I also think that it is important to provide a possibility of
full epubcheck conformity, even if it is not the default.  For the
release, however, I think that it is too late.

Here is my proposal:

1) for the release, we do not make any change to the code, but we
document that the EPUB we produce is no conformant.  We ship Daniel
patches in contrib/ and we document that they exist too.

2) after the release we fix conformance issues as we can/want, for
instance use CSS for border, add meta data for a publication date. I am
pretty sure there were other issues.  If there are still conformance
issues and we do not want to change the default HTML output, we add a
customization variable for epubcheck strict conformity and add the
corresponding code.

Does it look ok?
