Section 5.1.3 (XML output method, indent parameter) says: Whitespace characters SHOULD NOT be added in places where the characters would constitute significant whitespace -- for example,in the content of an element whose content model is known to be mixed. Perhaps it would be clearer to say "a validated element". In untyped data, all content is mixed, so it doesn't make sense to apply this rule. Note also a couple of typos in this para: the use of "--" for em-dash, and the missing space after the comma. Michael Kay
The XSL and XQuery working groups discussed this bug in the Aug 30 teleconference and felt that no change is necessary because the serialization specification currently does not contain text that distinguishes validated and unvalidated content. Making such distinction might cause other problems which the working groups would like to avoid. Your editorial suggestions were accepted.
