As recommended by W3C we are manipulating XML 1.0 in XAR format but
what I did not know is that XML 1.0 does not support all possible
characters (I tough at worst it would simply be encoded as a UTF8
entity but seems not) and we just got a report of Woodstox failing
because of some character it cannot write in XML 1.0 (""Invalid white
space character (0x1) in text to output (in xml 1.1, could output as a
character entity)").
So I'm wondering if we should move to XML 1.1. It's critical IMO that
we are able to export anything that can be stored in XWikiDocument and
in the database and it's the case here.
In theory this is most probably a breakage for people using a XML 1.0
parser but not sure how breaking it is in practice.
WDYT ?
I'm +1 for this but I won't apply it until I get more point of view
(ideally from people having more experience that me on XML 1.0 vs
1.1).

export the character "0x1" ???
This seems like a character for the old 7-bit-modem-based terminals.
I believe this one should just be prohibited at the entrance level.
I do not know of any valid meaning for this character.
Do you have such?

No I don't have any valid use case for this character (did not even
know what it was) but what I know is that you can have it :)

Note that it looks like the old packager plugin (based on dom4j) does
not complain and produce a  in this case (which the XML parser
does not like too much...).

I just checked https://www.w3.org/TR/xml11/#sec-xml11 and I think the
breakage is acceptable.
Thanks,
Marius

I’m not an expert in XML 1.1 vs 1.0 but it seems acceptable to me. Maybe increase the
format version of the XAR spec to 1.3 (I think we’re at version 1.2 right now).
BTW I’d also list the various version formats
on http://extensions.xwiki.org/xwiki/bin/view/Extension/XAR+Module+Specificati… and
explain the differences, i.e. what changes each version brings.
Thanks
