In 5.1.3 we currently write: ------------------------------------------- This element shall be used 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. ------------------------------------------- I believe we should insert the word "only" since I think that is what is in fact intended: ------------------------------------------- This element shall be used 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 only for the second and all following SPACE characters in a sequence.
