Granted, but it does use "S", which is used throughout the XML
recommendation to mean "semantically insignificant whitespace".
There is an implicit separation between the one-or-more whitespace
characters expressed by "S" and the remaining characters.
What you said would be better represented by
((#x20 | #x9 | #xD | #xA) (Char* - (Char* '?>' Char*)))?

I firmly believe that it is only the experience of implementation
that shakes out these deficiencies. A formal specification is
essentially a piece of code that the creator believes has been debugged
when it has been desk-checked.
