FWIW, James Clark's program dtdinst, which transforms XML DTDs into
instance syntax intelligently, identifies the following PE purposes
(based on top-down analysis, not bottom-up lexical recognition):
model group
attribute group
attribute default value
attribute type
enumerated values
INCLUDE/IGNORE flag
attribute or element name
other
overridden
"Other" is integrated and not represented; "overridden" is for
entity declarations that are overridden by earlier ones.
