Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8a5) Gecko/20041023 Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.7.3) Gecko/20041014 Firefox/0.10 An XHTML 1.0 or 1.1 document is rendered as XML pretty-print when <html> tag is missing xmlns= attribute. In XHTML DTDs this attribute has default value specified. Which means it's value is known when the attribute is omitted in the document. Also the attribute is of type #FIXED, which means that if a different value is provided, XML parser should raise an error, which Mozilla doesn't do. But since we're not a validating browser, this is irrelevant, though I think pretty-print is not the best reaction to this either. Here are the relevant DTD definitions: XHTML 1.0: <!ELEMENT html (head, body)> <!ATTLIST html %i18n; id ID #IMPLIED xmlns %URI; #FIXED 'http://www.w3.org/1999/xhtml' > XHTML 1.1: <!ENTITY % XHTML.xmlns "http://www.w3.org/1999/xhtml" > <!ENTITY % XHTML.xmlns.attrib "xmlns %URI.datatype; #FIXED '%XHTML.xmlns;' %XLINK.xmlns.attrib;" > <!-- html: XHTML Document Element ...................... --> <!ENTITY % html.element "INCLUDE" > <![%html.element;[ <!ENTITY % html.content "( %head.qname;, %body.qname; )" > <!ENTITY % html.qname "html" > <!ELEMENT %html.qname; %html.content; > <!-- end of html.element -->]]> <!ENTITY % html.attlist "INCLUDE" > <![%html.attlist;[ <!ENTITY % XHTML.version.attrib "version %FPI.datatype; #FIXED '%XHTML.version;'" > <!ATTLIST %html.qname; %XHTML.xmlns.attrib; %XHTML.version.attrib; %I18n.attrib; > <!-- end of html.attlist -->]]> To reproduce, see attached testcase. Expected behaviour: Render XHTML documents with missing xmlns= attribute. Current behaviour: Document is pretty-printed.

A valid XHTML 1.1 document with a missing xmlns= attribute on <html> tag.

INVALID. You can't have a valid XHTML document if it doesn't have an xmlns attribute, since without an xmlns attribute, the element isn't in the XHTML namespace. See XHTML 1.0 section 3.1.1 subitem 3, and Namespaces in XML 1.0, section 4, subsection "Namespace Constraint: Prefix Declared", paragraph 2, sentence 4.
