Empty AttlistDecl

[Stefan Mintert]

Hi!


Production [52] of the XML spec reads

       AttlistDecl ::= '<!ATTLIST' S Name AttDef* S? '>'


A legal AttlistDecl would be

	<!ATTLIST>


What's the purpose of an empty AttlistDecl?
Shouldn't production [52] read instead as follows?

       AttlistDecl ::= '<!ATTLIST' S Name AttDef+ S? '>'

(+ instead of *)




Why was a "Possibly empty attribute definition list" (K.4.4.1, 
[142], ISO 8879 TC 2, http://www.sgmlsource.com/8879rev/n1955.htm) 
introduced in SGML with the latest revision?



Thanks in advance for any answer!



Bye,

  Stefan.
