xml-dev - PUBLIC identifiers in XML?

["Simon North" <north@synopsys.com>]

This is mostly likely a RTFM question, but the XML FAQ says:

    "No public identifiers in entity and notation declarations"

While the XML-lang says (page 22 in the dead tree version or see 
http://www.w3.org/pub/WWW/TR/WD-xml-lang#secA. for the 
borrowed electrons version):

    "No public identifiers in ENTITY, DOCTYPE, and NOTATION 
      declarations".  

but at the same time, XML-lang explicitly includes PUBLIC in the 
production rule (Section 4.3.2, page 18 or see 
http://www.w3.org/pub/WWW/TR/WD-xml-lang#sec4.3.2) AND 
has an example of an external entity declaration that *does* use a 
public identifier.
 
I've also seen public identifiers used in DOCTYPE declarations for 
XML, and I had understood that this was OK but should still be 
supported by a SYSTEM identifier. 

I had also heard/read somewhere that a resolution mechanism for 
public identifiers was being worked on and that the restriction might 
then go away. 

Could someone please enlighten me on this?

Thanks.
