Bill has already replied pointing at the XSL stylesheet which helps address many of the problems with cross browser support, but I may comment on some of your individual points. a. Convert all symbolic entities to the corresponding unicode (e.g., 'ℏ' to 'ℏ'). This is probably a good idea anyway as it saves the reader having to read the DTD, however it isn't strictly necessary as long as you use a doctype whose final path name ends "mathml2.dtd" in this case mozilla (although it won't read the specified dtd) will read its own copy of the mathml dtd. b. Delete 'mml:' in all MathML commands and adjust the <html> tag accordingly. You should not need to do this (and you don't need to do that for IE, amaya, mozilla or netscape) c. Correct <math> tags if they do not specify xmlns. Yes the mathml should be in the mathml namespace, although if you use a prefixed form you only need declare the namespace once at the top of the file, not in every math element. d. Add the reference to mathml.xsl or pmathml.xsl if missing. That helps. e. Rename the file to *.xml, make it XML compliant actually the name doesn't matter, what matters is the mime type, although using a file extension of .xml is an easy way to get the right mime type. (add <?xml>, That isn't necessary unless the file is in a non default encoding, in which case it is needed for the file to be XML, not a specific restrication for mathml. convert all tags to the lower case, etc.) all element names in xhtml and mathml are lower case so this is just a requirement of the specifications not a workaround to get cross browser support. (remove unnecessary <style>, <object> and <?import> tags, etc.) well, if they are unnecessary then you can remove them, but they should do no harm if they are there as long as the contents are well formed xml. 2. a. Combine xhtml-lat1.ent, xhtml-symbol.ent, xhtml-special.ent and mmlalias.ent into a local DTD, say, math.dtd. b. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN" "math.dtd"> if you call the file "math.dtd" then mozilla will not read it unless you copy the file into the $MOZILLAHOME/res/dtd directory on the client. If you had called the file mathml2.dtd (or used the official mathml2 dtd) then as I said above, mozilla will read its mathml2.dtd that is in teh distribution $MOZILLAHOME/res/dtd directory. a. http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd is not properly parsed by MSIE (it does not understand IGNORE tag). two points here, there is an updated DTD in http://www.w3.org/Math/DTD/mathml2 (as specified in teh mathml errata) and if you update to IE6 SP1 the bugs in its XML parser are fixed so it can parse th edtd. b. Mozilla never loads external entities from the web, so you can not create a custom <!DOCTYPE> either. true but if you call your dtd mathml2 mozilla will read a dtd that defines all the mathml entities.
