Sure they do. There's just no way to declare them once and for all:
the declaration must be repeated for every element, as here.
Remember that "global attribute" does not mean "universally applicable
attribute" but rather "attribute with (by convention) a universal
meaning."

Just so. One might have a global attribute such as "iso4217:currency"
that is applicable only to a few attributes in a particular DTD,
those which represent money amounts. But its meaning would be
universal: an ISO 4217 currency code.
