I don t know of any translators for custom flavours of TeX and MathML If they exist then there are very few in the vast majority of cases choosing the application from MathType s compatibility menu just switches between copying raw TeX MathML or TeX wrapped in an HTML tag Maybe there are other cases like the Wikipedia one mentioned in the article the output is just TeX as usual but wrapped in a wiki tag This is hardly a custom translator and definitely not a microformat The text that I removed recently misrepresents this BTW if you wrote it what is EGO The fact that MathType has presets to choose the right import export format is still nice and worth mentioning so long as it s honest what it is It s currently mentioned at the end of the end of the section on application support but maybe it could be made a bit more prominent However it would be nice to keep the current structure of one paragraph each for Windows desktop Mac desktop and web applications or at least have a well thought out replacement structure rather than just plonking this fact at the start or end of the section A big problem with all this is that there s no reliable source for any of this Design Science s website just claims compatibility with 600 applications without breaking down which ones have genuine embedding support like OLE and iWork 09 which ones have special translators of some sort and which are just generic copy paste TeX and TeX tags Their works with page has products in all categories Indeed the majority are just websites that allow image tags and saying that MathType is compatible with these is a long stretch It even includes applications where the only option is to export an image from MathType and import it into the application e g Flash InDesign OpenOffice for Mac No one outside the Design Science marketing department would call these applications compatible
