[errata] html-1, html-2

The DOM Level 2 HTML [1] errata has been updated with the two following
additions:

html-1. 2005-01-19. [clarification]. HTMLImageElement.src.
        The word: URI should read absolute URI 
        
        (ditto for HTMLImageElement.longDesc)
        
html-2. 2005-01-19. [error]. XHTML and the HTML DOM.
        
        The sentences:
        
                For instance, element and attribute names are exposed as
                all uppercase (for consistency) when used on an HTML
                document, regardless of the character case used in the
                markup. Since XHTML is based on XML, in XHTML everything
                is case sensitive, and element and attribute names must
                be lowercase in the markup. 
                
        
        should read
        
                For instance, element names are exposed as all uppercase
                (for consistency) when used on an HTML document,
                regardless of the character case used in the markup. The
                names of attributes defined in HTML 4.01 are also
                exposed as all lowercase, regardless of the character
                case used in the markup, but for other attributes (i.e.
                ones that are not defined by HTML 4.01), the character
                casing is implementation dependent. Since XHTML is based
                on XML, in XHTML everything is case sensitive, and
                element and attribute names must be lowercase in the
                markup.
