HTML 4.01 Specification - query

Not sure if this is a typo or my mistake.  Section 7.4.2 of 
REC-HTML401-19991224 has:

	<!ELEMENT TITLE - - (#PCDATA) -(%head.misc;) -- document title -->

where

	<!ENTITY % head.misc "SCRIPT|STYLE|META|LINK|OBJECT" -- 
repeatable head elements -->

I don't see why -(%head.misc;) is necessary in the element definition 
of TITLE.  If it is necessary, why is it not also necessary to forbid 
all other elements besides those in %head.misc;?  One source of my 
confusion is that I am not sure exactly what PCDATA means.  As far as 
I have been able to discover, PCDATA may contain character references 
such as &lt; but no tag-based markup such as <EM>...</EM>; which is 
consistent with -(%head.misc;) being unnecessary.
