I don't recall this from a telecon, but two relevant messages from the
list are:

http://lists.w3.org/Archives/Public/www-webont-wg/2003Mar/0088.html
http://lists.w3.org/Archives/Public/www-webont-wg/2003Mar/0089.html

If the assumptions in those mails are correct (and there were no
follow-ups to suggest the contrary), then I think that allowing structure
sharing makes validation *easier*, as you don't actually need to check
whether it's happening or not.
