Can a CDSect be split across entity boundaraies?

[Jeff Rafter <lists@jeffrafter.com>]

 >>A consequence of well-formedness in [E14]general entities is that the 
logical and physical structures in an XML document are properly nested; 
no start-tag, end-tag, empty-element tag, element, comment, processing 
instruction, character reference, or entity reference can begin in one 
entity and end in another.<<

CDSect is not mentioned (or CDStart/CDEnd). Should it be? I couldn't 
find any other ommissions so I wondered if this had significance. I have 
given up understanding this on my own.

Thanks,
