undeclared entities?

I don't remember the following problem being pointed out, apologies if
it's a duplicate:

In section 3.2.6.1 of the MathML rec the following entities, among others,
are introduced:

IndentingNewLine
GoodBreak
NoBreak

however they do not appear as non-marking characters in chapter 6, neither
they appear in the entities list nor in the MathML DTD.

Yours,
Luca
