           Summary: xhtml namespace declarations on html nested within in
                    foreign content
           Product: HTML WG
           Version: unspecified

5.1 Element-Level Namespaces
says that the only namespace declarations used should be on <html> <svg> and
<math> but the xhtml namespace must be declared on any html elements used as
children of svg or mathml elements.

so

<math xmlns=".....">.....<mtext>...<b xmlns="http..xhtml">zzz</b>...</mtext>...

otherwise the html parser will put the <b> in the xhtml namespace (and it will
work) and the xml parser will put <b> in the mathml namespace (and it won't
work)
