XML Pocket Reference by Robert Eckstein If you have technical questions or error reports, you can send them to booktech@oreilly.com. (Please specify the printing date of your copy.) This page was last updated on July 5, 2000. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification Confirmed errors: {20} 3rd paragraph of xml:lang: Change the path in the reference from http://ds0.internic.net/rfc/rfc1766.txt to http://www.ibiblio.org/pub/docs/rfc/rfc1766.txt {33} ID and IDREF: would be useful to point out that IDs must start with a letter, and can only contain (I believe) letters, digits, underscore. Insert the following sentence after "...as IDs and ID references." "These types must start with a letter and can only contain letters, digits, and underscores." (50) last paragraph: The paragraph states that "The element has three primary attributes that can be set: count, level, and format." This line should read "...four primary attributes that can be set: count, level, from, and format." This is supported by the discussion of the "from" attribute on page 52. {93} example at bottom of page: these sites should be these sites (Swap the lines.)
