Bruce,
Reviewing Rintze’s careful notes on the changes made to the schema, it
looks like two features slated for removal have snuck through into
RC1.
http://xbiblio.svn.sourceforge.net/viewvc/xbiblio/csl/schema/trunk/csl.rnc?revision=1126&view=markup
One is the start/end attribute for names, at lines 318-22. This was
originally added to implement the AGU sort, I think. Can’t think of
any other use cases for it.
The other is the class attribute on the group element, at lines
615-16. This is not used in current Zotero, and there’s no longer a
reason to retain it, with the enchancements made to the display
attribute.
In haste,
Frank
