Yes, this seems to be a bug. W3C declares xi:fallback as:
  <!ELEMENT xi:fallback ANY>
  <!ATTLIST xi:fallback xmlns:xi CDATA 
     #FIXED "http://www.w3.org/2001/XInclude";>
which means that it can contain anything. Another xinclude certainly belongs
into the group 'anything'.
Please log this in the bugzilla, so it won't end up forgotten.

Ciao,
