* Gellmu: uses a TeX-like input. It does not seem to include any <annotation> element. The documentation mentions possible generation of semantics info in the future, so probably something like content MathML or OpenMath. See http://www.albany.edu/~hammond/gellmu/glman/glman.xhtml#SU-9.2.6
* LaTeXML: adds the LaTeX code inside math@alttext as well as an <annotation> with encoding "application/x-tex". LaTeX macros are expanded.
* LaTeXML: adds the LaTeX code inside math@alttext as well as an <annotation> with encoding "application/x-tex". LaTeX macros are expanded. If you request the math to be converted into parallel markup, the alternative forms will be encoded into annotation-xml. A typical example would be Presentation MathML as the 1st child and Content MathML and/or OpenMath as annotations.
* Maple: Seems to generate "MathML-Content" in <annotation-xml> and "Maple" in <annotation>: http://www.maplesoft.com/support/help/Maple/view.aspx?path=MathML/ExportContent

* blahtex: By default Blahtex(ml) does not use any annotation. If the --annotate-TeX option is used an <annotation> with encoding "TeX" is created. The LaTeX macros are expanded. It is also possible to use the --annotate-PNG option to generate an <annotation> with the URI of a PNG representation of the formula.
* itex2MML: does not include the LaTeX code, but Jacques Distler told me he plans to implement that in the future and suggested that Gecko support copy and paste. itex2MML does not support LaTeX macros. itex2MML is used, for example, in instiki and Abiword. itex2MML also uses the <semantics> trick to embed foreign content (e.g. SVG) in MathML.
* The Wiris OpenMath Editor tuned for the ActiveMath learning environment uses the semantics by creating a map of the (safe) types (including pictures, text, mathml-p & -c, openmath) then fetching from the first available in the following list: openmath, mathml-content, mathml-presentation, text, pictures.
