<!-- CHANGE INFORMATION
17 july 2005: ishida@w3.org
	- Reduced the content model of resources to just include multiple resource elements.
	- Changed the resource element to make bibref optional.

<!-- ins and del are added here rather than the @diff scheme because
it is easier (quicker) and more precise for marking up text (if using XMetal - just
highlight the appropriate text and double-click the element in
the element list).  It also make life much easier to convert to xhtml using xsl
than using a common attribute. -->
