I am reporting http://drupal.org/documentation/modules/book to moderators because:
HTML5 Validation Error in Book Module
I got the following error message when validating the HTML pages rendered by the Book Module.
"Line 15, Column 71: Bad value up for attribute rel on element link: Not an absolute IRI. The string up is not a registered keyword or absolute URL."

Since the value “up” is no longer available in the tag link for HTML5 (http://www.w3schools.com/html5/att_link_rel.asp), I modified the book.module file replacing “up” by “ stylesheet”, and it worked.

Would this modification be included in the source code?

Thanks,

As it happens, the REL links on the "book" documentation page is provided by the "book" module itself (part of Drupal core). This is not a custom Drupal.org feature, so it's something that would have to change in that module - though I'm not sure what the appropriate fix would be, if any. Removing the "up" link altogether would allow the pages to validate but it seems like a bit of a loss.

Note, even though this bug was raised against Drupal.org (running on 6.x), I've had a quick look in the 7.19 release and the code adding the HTML head link still seems to be there (lines 1107-1112 of book.module).

(Side note: Here's a better link to allowed keywords and their meanings from the current HTML5 spec.)

Version: 7.19 » 7.x-dev
