possible error - XHTML1.0 Exten....2nd_edition.

Sir,
I'm translating to brazilian portuguese the "XHTML 1.0 Exten.....Second Edition" and it seems that are an inconsistent there.

Item C.2. Empty Elements 
says:
Include a space before the trailing / and > of empty elements, e.g. <br />, bla...bla..

Item  4.6. Empty Elements (here the recommendation above wasn't applied!!)
Empty elements must either have an end tag or the start tag must end with />. For instance, <br/> or <hr></hr>. See HTML Compatibility Guidelines for information on ways to ensure this is backward compatible with HTML 4 user agents.

CORRECT: terminated empty elements

<br/><hr/> 

Regards,
Mauricio
