Was that > an anomaly? IE chokes on the *real* DTD which declares the plane 1 entities from Unicode 3.2, as MathML 2 is supposed to. However David C. prepared a modified version of the *combined* XTHML+MathML dtd in which these entities are declared to be in the private usea area of the BMP. That let's IE read the DTD. The point is this: if you want a single file that works in both NS7/IE6+MathPlayer, say, then you need the following: 0) a proper XHTML + MathML document with a 1) DOCTYPE (to the modified DTD IE6 can read), 2) MathML namespace indicated via a prefix, 3) MathPlayer object tag, 4) Processing instruction binding MathPlayer to the MathML namespace prefix The killer is that this single file has to be served as XML to NS7 and HTML to IE6, which requires server-side trickery or something. So, the better alternative is to use David's stylesheet which does the MIME type switching for you client-side. And, since it can write out the other declarations as well, you don't have to put in the awkward bits that have to be ignored by one browser or the other when preparing a single, common file. So, going this route, you need 0) a proper XHTML + MathML document with 1) no DOCTYPE (which means you can't use entity names) 2) MathML namespace indicated whatever way you find most convenient 3) the stylesheet processing instruction (and stylesheet, of course) Anyway, that's my summary of the situation. And, just to finish it off, I include minimal sample docs below, showing each method: ---------------------------------------------------------------------- Document which works in both IE6 and NS7 if served with the appropriate MIME type for each ---------------------------------------------------------------------- <?xml version="1.0"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN" "http://www.w3.org/Math/DTD/xhtml-math11-f.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:m="http://www.w3.org/1998/Math/MathML"> <head> <title>An xhtml+dtd example</title> <OBJECT ID="MathPlayer" CLASSID="clsid:32F66A20-7614-11D4-BD11-00104BD3F987"></OBJECT> <?IMPORT NAMESPACE="m" IMPLEMENTATION="#MathPlayer"?> </head> <body> <h2>An xhtml+dtd example</h2> <m:math> <m:mi>y</m:mi><m:mo>≈</m:mo><m:mfrac><m:mi>x</m:mi><m:mn>3</m:mn></m:mfrac> </m:math> </body> </html> ---------------------------------------------------------------------- Simpler Document which works in both IE6 and NS7 when used with David Carlisle's stylesheet ---------------------------------------------------------------------- <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="pmathml.xsl"?> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Universal Math Style Sheet example (no DTD)</title> </head> <body> <h2>Universal Math Style Sheet example (no DTD)</h2> <math xmlns="http://www.w3.org/1998/Math/MathML"> <mi>y</mi><mo>≈</mo><mfrac><mi>x</mi><mn>3</mn></mfrac> </math> </body> </html> --Robert ------------------------------------------------------------------ Robert Miner RobertM@dessci.com MathML 2.0 Specification Co-editor 651-223-2883 Design Science, Inc.
