(It is _not_ because it's "the later declaration"!): The attribute-list declaration for element type FOO: <!ATTLIST FOO BAR CDATA "XYZZY"> is read _first_ because it is in the internal DTD subset, which is processed before the external DTD subset. So the attribute definition for the element type BAR takes precedence over that given in the other attribute-list declaration for FOO: <!ATTLIST FOO BAR CDATA "BAZ"> because "the first declaration is binding and later declarations are ignored". Note that it is the _whole_ attribute definition: BAR CDATA "XYZZY" which is used, not just the default value as you suggest. (The two attribute declarations might have specified different attribute types.) Sorry to have caused confusion in the first place!
