"For interoperability, writers of DTDs may choose to provide at most one 
attribute-list declaration for a given element type, at most one attribute 
definition for a given attribute name, and at least one attribute 
definition in each attribute-list declaration."
Should this read:
"...at most one attribute definition for a given attribute name in an 
attribute-list declaration,..."
As it is currently, it seems to imply that no two elements in a DTD can 
have attributes of the same name, which is obviously wrong.  For example:
   <!ELEMENT div ANY>
   <!ATTLIST div
             class NMTOKENS #IMPLIED
   >
   <!ELEMENT span ANY>
             span
             class NMTOKENS #IMPLIED
   >
should be legal.
