As with string-join (bug 5597), the result shown for the first example of fn:normalize-space in section 7.4.5.1 contains extraneous space characters:  the result given is " The wealthy curled darlings of our nation. " but should be "The wealthy curled darlings of our nation."

In addition, the same mark-up problem occurs in section 7.4.1.1 in the second and last examples for fn:concat, and in section 7.6.3.1 in the seventh, eighth and ninth (the last three) examples for fn:replace, though in these examples the problem is much less likely to cause confusion.
