5.1.1.1

5.1.1.1 reads:
------------------------------------------------------------------------
This element is required to represent the second and all following SPACE
characters in a sequence
of SPACE characters.
Note: It is not an error if the character preceding the element is not a
white-space character, but it is
good practice to use this element for the second and all following SPACE
characters in a sequence.
------------------------------------------------------------------------
 Do we really mean to have a pointless note, or are we really intending
to say:

------------------------------------------------------------------------
Note: It is not an error if the character preceding the element is not a
white-space character, but it is
good practice to use this element only for the second and all following
SPACE characters in a sequence.
------------------------------------------------------------------------

Note the insertion of the word "only".
