The "in foreign content" insertion mode section of the HTML5 spec has some additional exceptions we should probably account for in the polyglot spec (http://dev.w3.org/html5/spec/Overview.html#parsing-main-inforeign). Specifically: 1) The list of conditions causing a switch to secondary insertion mode (children of <foreignObject>, <desc>, etc.) 2) The list of elements forcing a foreign content section to close (<b>, <big>, etc.) For (1), I suggest we state that the XHTML namespace must be explicitly declared on children of <foreignObject>, <desc>, etc. unless the child is a <math> or <svg> element. This would require removing/rewording the statement in section 5 indicating that no elements other than <html>, <svg>, and <math> should have namespace declarations. The listed cases for MathML elements would need to be handled in the same manner unless the child element is <mglyph> or <malignmark>, in which case no additional namespace declaration is necessary. The condition for <svg> inside <annotation-xml> would not need to be mentioned as the polyglot spec already requires that all <svg> elements have an explicit SVG namespace declaration. For (2), I suggest stating that elements such as <b>, <big>, etc. must only be used as children of HTML elements. The <font> element would be an exception so long as it does not have any of the attributes "color", "face", or "size". -Tony
