Need response to request for 1.0 erratum

The instance() function description in Section 7.11.1 says:

An XForms Model can contain more that one instance

and should say

An XForms Model can contain more than one instance.

This is fixed in the editors draft of XForms 1.1, but a www-forms-editor 
email 
(http://lists.w3.org/Archives/Public/www-forms-editor/2007Jul/0010.html) 
clarified that it was a request to fix 1.0.

Would a diff-marked spec fix without erratum be sufficient?  Is an erratum 
needed for this small a change?
