(c) is not always true because DTDs are used for more things than just 
validation. For example, DTDs are used to define internal general entities, 
attribute defaults, and attribute types.  (The latter is important, for 
example, if a processor expects to build links based on ID/IDREF attributes 
or process according to notations.)
